with all this, I know im the slow engine. Not looking to compete or anything like that. but am looking to change it up a bit.
'Faster wheels' can help to ride faster or to reach the same speed with less effort.
The question is: How much?
For aerodynamics the usual cited ratio is 80% of the drag is caused by the rider and 20% by the bike. But I don't know which position of the rider and which kind of rider is the base for that. Wheels are an important part, but they are not the whole bicycle. Let's assume that they are responsible for roughly half the bike's drag.
According to your handlebar height in relation to your saddle height on your photo I assume that your riding position is more upright and "professional speed" probably is more or less twice as fast as your speed. Therefore the aerodynamic advantage of an optimised high end wheel set is very little in my opinion.
The situation for faster acceleration or better climbing due to the reduced weight of lighter wheels is similar.
Imho there wouldn't be a
huge objective benefit of a new wheel set for your bike. The DT Swiss 470db rims are good and relatively light rims - I use them in wheel sets here, too.
Michelin Pro 5 as an all rounder
That seems to be a real and noticeable upgrade.
Fortunately there is a comparison functionality on BRR:

In my experience Michelin tyres are relatively supple and riding with them is fairly comfortable.
If you want to use the tyres with inner tubes, then I suggest to try out TPU inner tubes.
Next if: If your frame and fork have enough tyre clearance, then I'd use wider tyres like 32mm with a tad less pressure. That adds comfort and reduces the rolling resistance a bit.
That's for the measurable part of the "new wheel set" story.
The other part is the psychological one: A new wheel set is more perceivable than just another piece of black rubber on the rim. (*) It might change the look of the bike and can nudge even more the thought "Yes, I'd like to ride
that bike. Now." So it could increase your enjoyment on the bike through the certitude that you've changed something on the bike, it got something new. I can comprehend that. And as I wrote before, a second wheel set can be helpful in more than one situation.

(*) The Michelin Pro 5 TLR is also available with the "classic" colour scheme, not just black. That would the make the new new tyre
very visible on your black bike.
