Spells for unfurling brocade magus?

So I built a strength/athletics based unfurling brocade magus, and am having a decent amount of fun with it, but I'm really struggling with the action economy in combat. The main issue is i want to use the cool trip/disarm/grapple properties, but i haven't gotten to even attempt one because casting a buff spell on myself like runic weapon, then entering arcane cascade, then using my spellstrike on a guy already takes 2 full rounds of combat and it gets even worse when I have to move. I'm thinking if I can find some buff/utility spells that either only cost one action or last long enough that I can cast them before combat then that'd really help, but it's really hard to search through my spell lists. I'd also love to have some healing spells because our party doesn't have a healer but idk if magus gets access to them because pathbuilder is very unclear about that. Basically I wanna be supportive to my party by casting buff spells on them and trip/disarming the enemies to make it easier for them but I don't know what spells are actually good because I came from 5e, and all the guides I can find are outdated because the latest update removed or renamed most spells they refer to lol.
