I am far from the definitive voice around here. When I did the upper/lower style 5/3/1 split, I preferred for my supplemental lift to either be FSL, SST, or a lighter version of the other main movement. I didn't program stuff like skull crushers or high pulls. I just superset rows and chins with the pressing movement and did some bicep/tricep stuff at the end if I felt like it or if the game on the TV at the gym was exciting.
Are you set on lifting four days a week? If not, you might like the full body template.
Most of the time I see people here advocate 5s Pro and/or full body after a layoff.
Your plan doesn't look suicidal. It keeps the volume down and hits the main lifts. The accessory work is different than what I would suggest, but who the hell am I? It seems like a Wendler-written 531 plan would be more efficient, but I'm not your coach. If you like blazing your own trail and writing your own plan, more power to you. Especially if that keeps you motivated.
But do consider some of his templates. They're pretty good.
