Ive been using a combination of ublock origin and privacy badger. Set badger to strict blocking of any tracking from youtube and i have not seen an ad or adblock popup in a week or two now

I use sonarr for a few weekly shows i watch and never had any big problems. I use torrents with jackett for my indexers. Downloading whole seasons works prefectly too assuming the show is popular enough to have seeders. Ive been recommended prowlarr over jackett but ive not had any reason to swap yet!
