I had a 2017 Cutthroat Force 1 build. My first upgrade was the wheelset. I put on a set of Roval Control Carbon wheels. It dropped over a pound of rotating weight and that was off of the higher end specced wheels. Yes, you could save significant weight from the wheelset/tires alone. I also ran another wheelset with 42mm gravel tires.
The Cutthroat is a sweet rig. I used it mostly for gravel riding and occasional Bikepacking. It’s fun on gravel, more comfortable and stable than a gravel racer, but a little slower. If you’re out on the course to challenge yourself, the bike will suit you just fine. If you’re aiming for a podium, it will hold you back. If bikepacking is your primary goal then get the Cutthroat. I really enjoyed my Cutthroat. I only sold it to get a Moots Baxter (similar setup just Ti).
As far as carbon wheel suggestions, you might check out Roval, Reynolds (have 20% discounts frequently), and Mercury.
