l2arc is a read cache. Slog only is for synchronous writes.

Depends on the file system, I know for a fact that ZFS supports ssd caches (in the form of l2arc and slog) and I believe that lvm does something similar (although I’ve never used it).
As for the size, it really depends how big the downloads are if you’re not downloading the biggest 4k movies in existence then you should be fine with something reasonably small like a 250 or 500gb ssd (although I’d always recommend higher because of durability and speed)

Thx. I use ext4 right now. I might consider reformating, but so many new words to reasearch before deciding that. I heard about ZFS, but not sure is that right for me since I only have 16 GB of RAM.
Downloads are 100-200 GB max, but less than 40 GB most of the time. I have 512 GB in use and 2TB SSD not in use, can swap them if needed
