Easy Installer is preconfigured to deliver that stable build for that phone. I do not remember seeing any ETA for stable to upgrade to Android 12 (S), but stable builds do have to advantage of an OTA Upgrade of Android version, with no need to format data.
If you wanted to change to Android 13 (T) dev / community build, you would really have to format data, so you might choose to do that before you spent too long setting the phone up “just right”. you would need to follow the CLI manual instructions already linked.
If your PC is Windows there is this: [HOWTO] Install /e/ on a Samsung smartphone with Windows easily.
I have omitted the chance that you might need to revert to Stock ROM before an Upgrade to Android 13 (T). You might check Settings > About phone > Tap on Android version and take a note of or screenshot Vendor Security Patch Level and Baseband version. You would need to check with a firmware supplier like one of these, to see that your phone is already on the latest available Samsung firmware, Software revision (SW-rev) they call it.
