Keep in mind many of the features and things tracked in most electronic logbooks aren’t really needed at the non-pro pilot level, and you often can hide them or just ignore them in many electronic logbooks if you’re “just” flying as a Private Pilot.
Depends on which ones, but a few have “Private Pilot” modes that turn off many columns and entries, and others you just skip them if they don’t apply.
So even though they look complex, that’s just to get the pilots who need to track all sorts of things you don’t as a new pilot, to buy the software or subscribe.
And of course the paper logbook has lots of columns that can be filled out, too, and there’s different paper logbook formats for both Private and Pro logbook types. But just skipping columns “seems” simpler because you’re used to that.
Most people aren’t used to ignoring 90% of what’s on the screen in software unless they’re low end Excel users. Ha. Joke. But true about Excel.
