I have the 2020 SC, strawberry jam, and 2023 secret santa collab all enabled. There are also a bunch of "X-helper" mods. I am assuming those are important to keep enabled, so would the best course of action be to disable one of the 3 collabs?

generally it's a good idea to keep ~1 large and 1 small collab enabled at max

helpers are generally fine, they usually don't use much graphics memory, whereas large maps and collabs use a lot
especially SC and SJ, they have a lot of graphics
the general recommendation is to just disable any collabs and maps you aren't actively playing; that won't hurt your save files, you may just have to enter the save file and press the up/down arrows to get to the map you want
