jpa2825 - could you mention what is your current wheelset that was destroyed? I don't see the specs anymore on the Trek site. What is the rim width? What is the front and rear axle standard? From the pictures it appears to be a centerlock brake rotor mount. You could rebuild your wheel with new spokes and rims if that option was overlooked.
I bought a second set of wheels for my 2021 Domane+ HP for gravel use, so I did a lot of research. I ended up with a custom built set of relatively high end components that was about $1,100 for the set. Certainly there are options for custom built, but expect a 4-6 week delivery time assuming the pieces are available. As I wanted a stronger wheel but not overkill I used a 28 spoke build with a 3 cross lace pattern.
I think the 2019 had the same clearance for wider tires as the 2020/2021, which means you can use 24 or 25mm internal width rims.
For more strength look for more spokes (I expect your destroyed setup was 24 spoke), a 3 cross lace pattern for more strength over a 2 cross, and definitely not a radial spoke pattern for the front wheel for this bike. Certain rim make/model are stronger than others, you can do your research, but look for something targeting "gravel" usage and it should be making the tradeoff for strength vs weight. Make sure the hubs are centerlock rotor mount if that is what your current setup has. Because there is hub design and manufacturing tolerance greater than your disc brake tuning and shifting tolerances, your bike will need a tune up with the new wheels. The brake calipers will need to be centered, and the rear derailleur H/L will need to be centered. Your disc brake rotors and rear gear cluster will of course need to be moved to the new wheelset.

I think these are interesting to compare. They don't mention spoke count, which is odd, but you can count them in the picture. You will see the the "g" or "gravel" is 24 spoke and 2 cross, and the "hg" or "hybrid-gravel" (which they mention as ebike specific) are 28 spoke and 3 cross.
These dt-swiss hybrid-gravel wheels look to me as a good example of a stronger wheel.
People talk about Hunt wheels. Their suitable offering is a 28 spoke 2 cross pattern. They talk about max weight on their spec page, so it is a good reference. Their delivery is a bit far in the future though.
