First of all, a big thank you to @dosdude1 and all the people involved in making it possible to install Mojave on unsupported Macs.
I just installed Mojave 10.14.1 on my MBP 5,3 with no drama at all using Mojave's Patcher. Setup went fine and everything works as expected (including the known issues, hehe).
I have a couple of questions:
1) Is the choice between APFS and HFS+ related to the ability to install OTA software updates?
2) Any warnings in regards of Software updates other than the fact that 10.14.x updates could break something?
3) Performance-wise what would be the best choice of file system?
Thanks!
1. APFS is required to install updates through the System Preferences software update, but downloaded updates like this work fine on either
2. Reapply patches after each update, and keep another functioning boot disk/partition in case "the feces impacts the ventilator"
3. APFS will allow instant "copying" of files due to its use of snapshots. HFS+ may perform slightly better, especially on old systems, but overall they are comparable.
This seems like a pretty good summary:

For what it's worth, I use HFS+. But I also don't use the patcher, so I might be a bit insane.

You need to have an APFS formatted volume in order to install macOS Mojave Updates via System Preferences. They could break your machine (which is why you will want a backup of your important data) but if you have the latest macOS Mojave Patcher (1.2.3 at this time) you should be set.
Performance wise, APFS is the best choice as its more modern and includes performance improvements across the board, especially for HDD's.
I think you meant especially for SSD's. Users with HDD's are actually recommended to stay on HFS+ because APFS can create a noticeable slowdown.
Also, even if an update "breaks your machine", your data is still safe -- just boot from another drive and copy it off. Having a booting OS is irrelevant to having your files. Although backups are always important!
