Why didn't you stay with pcloud, again? You mentioned encryption was uncomfortable, but in the end you selected nextcloud which doesn't have reliable encryption.

It’s the only solution I’ve been able to send at consistent 1Gbps speeds to (except when it’s many tiny files).
About encryption, you unlock it once per restart and it stays open. It’s not like you have to enter password every time you move a file..
(For the backups i use rClone with encryption)
I encrypt all my files locally before sending so the encryption doesn't matter for me.
I use rclone with --transfers 32 (for smaller files) and it seems to work fine without throttling.
