MacOS Suggestion

Hello!

I just picked up a MBP A1502 with a Core i7, 8GB of RAM (I plan to get more down the road) last week as I had two laptops crash in one week (lol, my luck 😅).

I currently upgraded it to Big Sur but was curious what the recommended MacOS I should upgrade to. I’d like to at least be able to run 10.5 so that I can get certain programs to work properly but I’m curious too on how well it would run Sequoia.
