Unison works well. https://www.cis.upenn.edu/~bcpierce/unison/

rsync is incredible efficient and reliable. I use Nextcloud for some things. But it is just too slow for large data (Gigabytes and tens of thousands of files). Especially it they change frequently. HTTP and webdav is slow and the clients are not reliable. Last week I tried to transfer 20000 photos (for Mapillary) from a phone using Nextcloud. It took forever and the Nextcloud app crashed after a few hundred photos. Rsync (syncopoli on the phone) worked like a charm and did the job in no time.

Plus it is just so convenient using SSH because you can easily make tunnels and still have end-to-end encryption.

Large sized files are not a problem with Nextcloud. Large amounts of files in a single directory are. A .git dir in nextcloud will trash performance.... but my photo library is perfectly performant :shrug:
