However, my biggest concern is the excessive SSD usage.
M1 users, what is your experience with the machine? Have you experienced any issue related to the SSD in these two years? I would like to get one, but I do not want to deal with data corruption during the lifespan of the machine (I suppose four years is a conservative duration).

This was a software issue, and was resolved in macOS 11.4 (in May 2021).
