Well done !
I’m missing my commute whilst I’m still WFHing. Looking forward to going back to the office for that reason.
Here’s a couple of thoughts ….
Do you have to leave your bike outside at work unattended ? This may affect your choice of attaching more things to your bike, the more you attach the more you have to remove once at work. Maybe easier to keep with the minimum panniers, or a backpack like I got to using.
I had lights, saddlebag, Garmin, pump etc etc attached, all of which I had to remove once I got to work which became a PITA. Luckily I wangled being able to take my bike into the building so it was no longer a problem.
I have a few of these in various sizes for keeping the smaller stuff in :

If you also ride outside of the commute, then have second toolkit etc so that you don’t have keep transferring it between bikes / bags, sooner or later you’ll forget something.
Leave as much stuff as you can at work, shoes, clothes, glasses, laptop, washkit etc etc. Replenish on those days where you have to drive in or make a special trip once a week.
Add some small (e.g. Leatherman) pliers to your kit perhaps to deal with those pesky nuts on tubless valves which get stupidly tight. Also some zipties, a small roll of tape (or a length of tape wrapped round your pump (or Co2 cart) and a spare battery for your lights/cadence thing if you use them.
Perhaps a knife for chopping off the end of those tubeless repair worm things.
I always use a CO2 inflator, but usually carry a pump too, just in case, somewhere in the bag.
Go tubeless if you can, far fewer punctures in my experience, irrespective of bike/wheel/tyre choice.
Mudguards, definately for the winter.
