welcome to the forum,
on android, i run rclone inside termux.
to connect the pc and android using wan, lan, wifi, i use tailscale.
as for ssh, termux has a built in ssh server, so easy to remote in over tailscale and write scripts.
between the pc and android, can use native smb.

else, if you want to run sftp server on pc, rclone serve sftp remote:
