Best 3rd and 4th ideas for Spain are usually Influence and Diplomatic for getting good alliances, potential personal unions, diplo annexing, and getting the votes to be Emperor of the HRE.
That diplo boost in Europe just makes you invencible, because Spain already has an excellent economic situation (if you are colonizing) and a good military (the iberian peninsula gives you enough manpower, your colonial nations gives you even more, and your national ideas have amazing military bonuses).
Alternatively, you can always go for Innovative idea group for obvious reasons, although it’s not the best idea group for Spain, because Innovative is really worth it when you pick it as first idea group, and Spain can’t afford that, as is mandatory to choose Exploration and Expansion as first 2 idea groups.
Religious ideas is recommended by a lot of people for Spain, but I disagree: Diplomatic, Influence, or even Innovative, are much more worth it as 3rd/4th idea. You can pick Religious ideas later.
