MBP 2015 Retina running Sierra and wanting to wait a bit on Catalina. Any big issues updating to Mojave to be aware of? The only thing I've read is external monitor trouble? I have my MBP hooked up to a Dell 24" via Thunderbolt. Am planning on doing a clean install. Thanks!
 
I have a late 2014 iMac that I went from Sierra to Mojave. I have a Benq 27" connected with DisplayPort and have had no problems at all with it. I too did a clean install and it went quite smoothly. I did however have a few minor software hitches but these likely are not the OS fault.

I figured I'd give it an evaluation first before I took the total commitment to the internal drive, so I formatted an SSD with APFS and then made two partitions. This APFS is really quite cool in the APFS formats the whole drive and then the partitions on the drive are sort of floating in you don't define a certain size, rather they can just virtually exist on the drive. My idea was to split off the users data from OS partition onto it's own. To move my user data, I did a CC of the users directory from my Sierra install over to the newly created User-Data partition. I created my user account then just changed the location of the home directory. Worked like a charm except for a few apps bombed. It turns out its a bug inside their code and not that I did it wrong. Also, I use Firefox and for some reason, it lost access to all my plugins. Easily fixed.

Quite liking the feel of Mojave. Working with the app developers to get there software fixed.
 
No issues for me when I upgraded to Mojave from High Sierra. I'm staying in the desert for the foreseeable future.

Never hurts to make a clone with Carbon Copy CLoner (or Super Duper) as a bootable back up before you start?

I have a MBP mid 2015 on Mojave that I migrated over from Sierra to High Sierra then later to Mojave. I did not bother with a "clean install" too much work installing all my apps from scratch and also digging up the serials etc and dealing with updates - all time consuming.

FWIW - Mojave works really well for me and I have no problem with external monitors (using thunderbolt to HDMI) - I use a 32" LG external monitor at home an often connect to larger screens in hotels etc. when traveling never had an issue with any external monitors.
 
I upgraded from El Capitan to Mojave. No problems. I love the dark mode.
 
Upgrading from High Sierra to Mojave on late 2014 13" MBP. A bit more responsive and more stable (I didn't update Safari though - remain at 12.1.2).
 
Sierra is basically El Cap with Siri. It’s kind of pointless to be in it right now. Mojave is smooth. Dark mode looks great. Catalina is garbage. I don’t think I will ever use it on my home machines.
