Sorry to kind of have an attitude with the "please don't suggest..."
-- I realized I could kind of do something like that.
as root, using bash I ran
#cd /home/lost+found
#echo "" > ~jholland/list; for i in `ls`; do file $i >> ~jholland/list; done
and then as me (jholland) I ran
cat list | sort -k 2 | less
So this gave me the list of the files with what they seem to be in
groups. I think a lot of them are browser cache, jpegs, pngs....I looked
at some of the gzipped ones and they were web pages and css files.
There are some that don't make sense, for instance #16251989 is listed
as "ISO Media " and contains binary data and then some HTML.
I will have the backup from a couple days ago back here in a week if I
need it.

I have a backup that is at least 2 days old offsite at a friend’s house. It
would be a bit of a pain to go retrieve it, but I could do that.
Short of that, I have 4000+ files in lost+found with names like #1094827.
What can I do with those? I tried running “file” on the first 50 via xargs and
they mostly at least purport to be some sort of intact file. How can I
determine what they are? Please don’t suggest that I manually use “file” and
then an appropriate program to examine each one in turn

I just had a kernel panic when reloading a firefox tab pointed at facebook.
After restarting, all the filesystems had errors but /home was particularly
bad and caused the boot to stop and prompt if I wanted to enter a root
shell.
I eventually got fsck to mark the /home filesystem clean but it found >4000
lost files that it moved to lost&found. I am not so experienced with this,
running "file" on a few of them shows that they may be intact files but they
have numeric names now.

A regular external backup would have saved your data no matter what
filesystem you might have been using. There are a few different backup
solutions available in the ports tree. I use restic, both on OpenBSD
and macOS.
