Post surgery and moving forward - recommended fitness please

I’m thinking a little further down the line as I’ve only recently had 2 lots of spinal surgery and am still in recovery.

Pre my back deciding to be tricky I was running, learning to box, lifting weights and swimming. I don’t feel confident lifting or running again. I keep reading Pilates or yoga are popular.

Can you please let me know what paths you all went down and whether there is a preference between Pilates or yoga.

Thank you
