Check out the community lemmyapps (not sure how to link yet), it has them all listed. I personally like Connect.

Yup, agree with this. I personally use Nextcloud but there are lighter solutions just for file hosting/syncing.
How does this work for a google account that I’ve got linked in gmail to my standard google account? Is that classed as active or do I need to login to each one manually still?
This is great, thanks for sharing. So is the intention to manually sub to any you want?
