Your setup sounds fine. Don’t let the aero frame hype get to you - the Emonda is a pure race bike with the H1 geo. The h2 is a bit more forgiving, but still fine. Honestly your setup sounds fine and I’d be more focused on having my nutrition, fitness dialed, and race smarts/tactics for these races. Sit in. Stay out of the wind, if you get up front do short pulls and get out of there. Make others do the work, chase, because they will.
My setup: Emonda SLR (rim) H1 with Bontrager Aelous 5 tubulars. I also have an Allez Sprint that’s rim. I don’t have a choice in helmet and kits due to partnerships, but the stuff we get is of nice quality and the helmets are fine.
Other stuff: I have some velotoze I use for TTs and my skin suit as well for TT, crits, and road races that I don’t need a ton of shit for pockets. As or that person who said be in your drops; What? If you’re comfortable sitting in your drops for the entire race, cool. But, being comfortable and conserving is more important. I’m rarely in the drops minus some descending, tech areas, and then attacking/breakaways etc. I’m in the drops a lot for crit racing though. And if you’re sitting in the pack out of the wind, you don’t need to be in the drops. Unless you want to be.
