I think Jerusalem should always have a higher weight than anything else except the Christian core regions of France, Constantinople and Italy. Jerusalem was the inspiration behind the whole movement, it's the holy city at the centre of Christian apocalyptic hopes and expectations. An excursion against, say, Yorkshire, isn't going to have the same effect.
Catholic, Fraticeli:
1. Italy (seat of the Pope)
2. France, Burgundy, Aquitaine, Bavaria, Lotharingia (very near to Italy and a long Christian history with a lot of Holy sites)
3. Greece (to reclaim Constantinople)
4. Jerusalem/Israel (The Holy Land)
5. England, Frisia, Hungary, Germany/Saxony, Norway, Sweden, Denmark (to mop up remaining heathen realms threatening western Europe)
6. Egypt, Syria, Africa, Anatolia, Poland, Pomerania, Bohemia, Finland, Lithuania, Sicily (Historical crusade targets)
7. Galicia (for Santiago de Compostela)
8. Navarra, Aragon, Asturias, Leon and Castille (once the middle east is taken, crusading can commence in Iberia)
9. Andalusia, Mauritania, Portugal
10. Ireland, Wales, Scotland and Brittany
11. Mesopotamia and Arabia (to finish off the Saracens)
11. Rus, Ruthenia, Bulgaria, Serbia, Croatia, Wallachia, Georgia and Armenia (filling in remaining gaps)
12. Alania, Cumania, Volga Bulgaria, Taurica and Nubia (hypothetical crusades)
13. Persia, Abyssinia
14. Afghanistan, Balauchistan, Khiva and Turkestan (consolidating Persia)
15. Tamilakam ('rescuing' the south Indian Christians)
16. Punjab, Sindh, Gujarat, Karnata, Maharastra, Andhra, Lanka (general offensive into India)
17. Delhi, Rajputana, Malwa
18. Kosala
19. Bihar
20. Bengal
21. Orissa, Kamarupa, Gondwana, Telingana (ridiculous jungle crusades)
22. Mali, Khotan, Mongolia (ridiculous steppe crusades)
23. Perm (THE GREAT ICE CRUSADE!!!)
I've started the Iberian crusades later, because historically the Reconquista was seen as something separate and Spanish Catholics were supposed to focus on that rather than running off to the holy land. Gameplay-wise it solves the problem of the whole Catholic world going back and forth trying to rescue little Spanish principalities instead of crusading in the east like they're supposed to. It would also be a good idea to get rid of the 'Germany not controlled' requirement since Germany is now lower down the pecking order than Jerusalem.
Sunni, Shia, Ibadi, Kharijite, Hurufi:
1. Arabia (Holy Land of Islam)
2. Mesopotamia (heartland of the middle east)
3. Egypt, Syria (to remove any crusaders from the environs of Jerusalem)
4. Jerusalem/Israel
5. Armenia, Africa, Persia (securing the borders of Islam)
6. Anatolia
7. Greece (the conquest of Constantinople)
8. Sicily, Serbia, Bulgaria, Taurica, Georgia (Historic targets of Ottoman expansion)
9. Mauritania, Andalusia (conquering Constantinople has a higher priority than securing Spain)
10. Aquitaine (briefly Umayyad territory)
11. Burgundy (historic Umayyad influence, encircling Italy)
12. Italy (the conquest of Rome)
13. Portugal, Galicia, Asturias, Leon, Castille, Navarra, Aragon, Bavaria, Croatia (mopping up)
14. France
15. Lotharingia, England (the last remaining major kingdoms within the old Roman borders)
16. Bohemia, Hungary, Wallachia, Alania (consolidating the northern frontier)
17. Germany/Saxony
18. Brittany, Wales, Ireland, Scotland, Frisia, Denmark (mopping up again)
19. Mali, Nubia
20. Khiva, Afghanistan, Balauchistan (turning to the east now that Christendom is mostly or entirely conquered)
21. Sindh, Punjab, Turkestan, Abyssinia
22. Khotan, Rajputana, Gujarat, Delhi
23. Malwa, Kosala, Cumania
24. Bihar, Mongolia, Volga Bulgaria
25. Bengal, Gondwana, Maharastra
26. Karnata, Tamilakam, Lanka
27. Andhra, Telingana, Orissa, Kamarupa (finishing off India)
28. Norway, Sweden, Poland, Pomerania, Lithuania, Finland (finishing off pagan Europe)
29. Perm (Impossible to do Ramadan up here!)
I've given Constantinople and the war against the Romans a higher priority than Andalusia, since conquering Rum plays a much more important role in Islamic eschatology and ultimately in history the loss of Al-Andalus didn't slow the Ottomans from invading eastern Europe, plus if the Christians aren't crusading in Iberia there's less pressure there anyway. The Muslim goals are more oriented around fighting the Christians than expansion against pagans and other heathens, but once Christendom is beaten the jihads turn to the east.
Zoroastrians:

11. Georgia, Bulgaria, Serbia

13. Andalusia, Bavaria, Cumania, Khotan, Kosala, Karnata, Maharastra, Malwa, Andhra, Lanka
14. Italy (Major obstacle)
15. Mali, Portugal, Galicia, Leon, Castille, Asturias, Navarra, Aragon, Aquitaine, Burgundy, Bohemia, Ruthenia, Volga Bulgaria, Mongolia, Bihar
16. France (Major obstacle)
17. Lotharingia (Lotharingia without France looks ugly)

19. England (Last major Catholic kingdom)
20. Brittany, Wales, Ireland, Scotland, Frisia, Denmark, Pomerania, Poland, Rus, Bengal
21. Norway, Sweden, Finland, Lithuania, Telingana, Gondwana, Kamarupa, Orissa
21. Perm
The Zoroastrians are more 'defensive' and land-oriented than the Muslims and Christians, so they mainly get Great Holy Wars that help them rebuild Persia and secure its borders.

Yazidis are non-Muslims, so they get a different list based on the Zoroastrian one.

Because the Vikings can attack very well over the sea and can travel down rivers, they have lots of disparate crusade targets across the world that don't necessarily border each other.
