I too have an Ender 3 Pro, I like it. I've also done a few upgrades, the biggest is the Micro Swiss hot end as Tim did for hotter filaments. For PLA the stock hot end is fine.
Other mods I've done were printed from files I found on Thingiverse. These were not only useful but good to gain experience in printing. I printed some feet that are springy, they help to quiet the printer depending on what it is placed on. A knob for the filament feed stepper motor-helps with filament changes to manually advance/back out the filament. The knob has Yoda on it. I also printed some cable-chain guides for the wiring to the bed and hot end. These are not necessary but I enjoyed printing them and as I said before, were something to gain printing experience with.
I also use Fusion 360 and have a few designs I did-non ship related. Very satisfying to envision something then see the physical creation of it!
Hopefully soon you will find the time to get it out of the box.
