I am not new to botw speedrunning but i played 1500 hours in 2020 and was mostly inactive in 2021 can someone suggest fun categories to run for my return? Im down to spend a while learning the route as long as its unique and fun (i love glitches)

Well new Great Plateau route is a good start, then maybe Bread% or all Dog Treasures. Once you are ready for longer runs, the new All Shrines route is fun.
