Want to start incorporating calisthenics with bouldering but struggling with choosing the right exercises

Hey all,

I've been bouldering since 2020, just recently took a break and it's currently been about 5 months since I last went bouldering and in that time I started to go to the gym. Now I'm looking at starting calisthenics and getting back into bouldering.

I've chosen a split that works best for me, I'll be doing an Upper/Lower split with calisthenics Upper and weightlifting lower that will look something like this with bouldering incorperated.

Sunday: Heavy Bouldering + skill day

Monday: Upper

Tuesday: Lower + Core

Wednesday: Casual/Light bouldering + light skill day

Thursday: Upper

Friday: Lower + Core

Saturday: Rest

I'm struggling to choose the exercises for the upper days though, I'm happy to switch the split if its recommended. I've tried to do research but I've just gotten overloaded with where to start.

A bit more information, I'd like to work towards the L-sit and human flag, would love to achieve those so I'm guessing I'll cater my exercises towards those but I'd also like calisthenics to assist with my bouldering.

Any idea on where to go or how to start? Would love to know if my split is good or not, happy to adjust but it currently works best with my life, job, and other hobbies.
