First thing I wanted to ask is: is there any way to make a backup of the phone before starting, or at least a way to bring the device back to factory settings if something goes wrong? If yes, how?

First, download the stock ROM (the one you are currently on) for your device. This way, you will be able to restore the phone very easily with Odin (needs Windows).

I don’t know a way to fully backup before doing anything. But once TWRP is installed, you can proceed to a full backup (system + data) (but not the internal starage, which is what you can access in the Files app or by plugging the phone to a laptop).

On the other hand, my understanding is that Lineage OS 17.1 supports Samsung S9+ with Android 10, with latest firmware. So should I be still able to install Lineage OS until /e/ OS is officially supported on my device?

Yes you are able to install LineageOS 10.

You may need to take a look at this howto, in case you have a confirmation and can proceed to a downgrade to install /e/, or to install LineageOS :
