My main concern is to keep track of “Versions” for files and folders, in order to be able to recover anything, even if erased today.

Let’s assume that I make a scheduled FULL disk image on every Sunday, followed by a DIFFERENTIAL backup on following day of the week (Mon Tue … Sat, of course scheduled)
If I want to restore a specific folder or a file version at a particular date, I assume this can be done by clicking right on the corresponding DIFFERENTIAL image to that day, then click “Explore” to browse to the wanted item to restore.

I understand that browsing is done by showing contents of a virtual disk, receiving an available drive letter given by Macrium Refect.
Actually one sees the full drive just as it was on that date; so I can restore each item I want. Right ? Or wrong ?

If there is an easier method to recover previous "versions" or even erased items, please mention it.
Thank you

No, you are not wrong. After a drive letter has been assigned, you can browse the desired backup via the standard Windows Explorer.
From then on, you can copy the files and/or folders by simply using copy and paste. No need to create a special restore job

^ Exactly. The Differential backup file itself contains only the data that changed since the last Full, but when you mount a backup as a virtual drive, you still see the entire drive as it was at the time the Diff backup was captured, because Reflect in the background is synthesizing the Full and Differential backups together in order to create that state, just as it would if you decided to restore that backup. That’s why you need the parent Full available in order to mount or restore a Diff.

There’s no way to mount a Diff backup in a way that reveals only the data that was captured in that backup. That wouldn't even really be feasible for image backups since they operate on a block level, so in many cases if you did that with a Diff, you’d end up with a few data blocks of a lot of files, not complete usable files — and maybe not even a complete usable file system. File and Folder backups always contain whole files, but even they always show the whole source data set when mounted, not just the files that that specific backup contains.
