That is not that helpful when you are on the console, or even when you are in a ssh session since you have to then switch to some other program to check. Is there really no way to list the current versions other than accessing a web page?

Yes, something very much like this without having to go 'off-server' for a web browser or do some scraping along the lines of

 wget -q -O- https://www.freebsd.org/releases/ \
	| grep "Production Release:" \
	| awk -F'>' '{print $4}' \
	| sed 's/.\{3\}$//'
12.1
11.3

Or

wget -q -O- https://www.freebsd.org/releases/ \
	| grep "<p><b>Release " \ # or grep "Release [0-9]"  if you prefer
	| awk '{print $2}' \
	| sed 's/.\{4\}$//'


Which is bound to fail at some point. (Sooner more likely than later.)
