Honestly most collectathon platformers are a joy to 100% and were even designed for it. Mario 64, Banjo, Spyro; all really fun and rewarding games to 100%.

Jak & Daxter: The Precursor Legacy
Even if a bit dated, the graphical style holds up quite well, the game is pure enjoyment to explore and rather trivial to 100%. Even extra cutscene for findkng all Power Cells.
