Haven't made it all the way, but I was able to find a way to downgrade my Google One back to the $2/m for extra storage. YouTube will remain to avoid ads. Everything else has been switched or is being worked on, but after 20 years it takes longer than I imagined.

Still looking for my cloud provide, leaning towards digital ocean.
