Size of 2 MP4s is radically different (bitrate)

I'm trying to decide which version of a file to keep... bitrate/quality question
Hello Handbrake community! This is less about handbrake, and more about video quality... so I hope it's OK to post this here. Apologies in advance if not! I'm hoping to draw on your significantly greater experience.
I have a bunch of video files that I've been slowly but surely converting to the same MP4 format (for ease of playing... I have a lot of Apple gear). I've been using the Apple 2160p HEVC format (which I also understand is H.265... although don't understand what it's sometimes called HEVC and sometimes H.265! As with the MKV files).
Anyway - I accidentally converted a file that was already an MP4 with this setting, and I noticed the file size dropped from 1.3gb to a little over 100mb. Of course, I panicked... as I worried I had suddenly been converting a bunch of files and losing lots of data! I compared the two bitrates in Quicktime... and yep... the smaller file is 2.43MBits/s and the larger one is 32.20MBits/s. So I've lost some data... but... on reading and checking again all the settings (I use constant quality RF at 24 usually), I think I shouldn't have lost much, if any, noticeable data?
I'm trying to preserve these files with as much information as I can - but not at production level standard.
Could anyone confirm I've not messed this project up please? And or double check my settings to see that I'm in the right ball-park? Should I set it to RF 20?
Thanks in advance!
