24yo, 800 FICO, $80k income, heavy driver (25-40k miles/year) — best card to add for gas + hotels? (Current setup listed)

I'm 24 with an 800 FICO and $80k income. I drive a lot — 20-30k miles for work (gas fully reimbursed) plus 5-10k personal. Work travel means lots of hotels and restaurants. I also take 1-4 personal vacations (remote work on these "vacations" lol) per year flying on cheapest airline. Current cards:

• Discover It — $5,800 limit, 3 years 10 months old
• Capital One Savor — $9,000 limit, 1 year 5 months old (3% on restaurants/groceries/entertainment — I use this heavily)
• 5/3 regular card — $2,300 limit, 4 years 10 months old (flat 1.25% cash back, barely use)
• 5/3 secured card — $300 limit, 4 years 10 months old ($42 annual fee, almost never use — planning to close or product change later)

I'm looking to add one more card now, focused on reimbursed gas/hotels/ or a card for travel from work travel. Restaurants are already covered well by my Savor (3%) and Discover it (5% rotating sometimes), so dining isn't a priority on the new card.. I've been looking at:

• Amex Blue Cash Everyday — 3% on gas (up to $6k/year), 3% U.S. supermarkets, 3% U.S. online retail
• Bank of America Customized Cash Rewards — 6% in chosen category (gas) first year, then 3% (can switch to travel for hotels)
• A card to rack up airline miles but not sure how that works since i dont fly for work.

Not sure i want another category card since I already manage Discover's rotating rewards but open if it makes sense. At some point I'd like to close one of the weak 5/3 cards and replace it with the Fidelity Rewards Visa Signature (flat 2% that deposits into my Fidelity investment accounts, where I keep my investments). Any strong recommendations I'm missing for heavy gas + hotels? Wells Fargo Autograph or Citi Custom Cash worth considering? Appreciate the help — trying to be smart with age of accounts since I'm young. Thanks!
