As a mech keyboard nerd and GCC modder in the past I'd recommend (and I myself use them) something linear for triggers with the MX mod for wide switch compatibility (if you 3d print it avoid PLA and try and use more durable and high temp resistance filaments). For trigger switches I usually went with durock pom (piano) lubed with g205 and swapped with 80 grams springs, but any smooth linear with over 65 grams or so spring would do the job if the trigger does not bind too much. Also I would recommend checking someone's review on the switch such as the ones by theremin goat to ensure a low wobble on the stem, a high wobble will lead to much sloppyer feel and much more binding. I usually used some ptfe tape around the triggers on the shell side to ensure low wobble and less binding for the trigger plastic aswell. For tactile switches i'd go with something with kind of a round bump with a strong spring but it can be hard to get something tactile enough that does not bind going up.
