Best for Cashflow: AMEX Plum, For extended payback periods without accruing high-interest rates, the Plum Card is beneficial as it offers a unique payment flexibility feature, allowing you to defer payment for up to 60 days without interest.
Best for PPC: No surprise, the AMEX Business Gold: This card is particularly beneficial for advertising expenses, offering 4X Membership Rewards points on the two select categories where your business spends the most each billing cycle, which can include U.S. purchases for advertising in select media, up to $150K, then you need to get another one (up to 10).
Best for Travel: The AMEX Business Gold will obviously give you the most travel rewards due to the high spend from Advertising. But if you're looking for cards specifically with travel rewards, check out the AMEX Business Platinum Card which is ideal for frequent travelers due to its extensive travel benefits like access to the Global Lounge Collection, $200 Airline Fee Credit, Fee Credit for Global Entry or TSA PreCheck, and luxury travel perks.
OR the Hilton Honors Business Card: If you prefer staying at Hilton hotels, this card offers valuable rewards and benefits like Hilton Honors Bonus Points, complimentary Gold status, and Free Night Rewards.
Best for Inventory Purchases: Amex Blue Business Cash Card: This card is excellent for inventory purchases due to its 2% cash back on all eligible purchases on up to $50,000 per calendar year, then 1%.
That being said, $50K isn't all that much in inventory purchases per year. For that reason, it's probably best to use the AMEX Plum Card due to the 2x as long payback period.
To summarize...

BONUS: For what it's worth: There are also payment services who, for a fee, will allow you to pay your supplier invoices via credit card.

Cashflow thought experiment:
> Invoice for $100K comes in. > Pay with 3rd party service, they charge 3% (or $3k) > Put on AMEX Plum, 60 day payback > + Whatever terms you have from the supplier. > Let's say it's 30% down and 70% landed.
That means you'll only have to pay $33K ($30K down + $3K fee) up front, and the other $70K in approximately ~100 days (60 Days payback on Plum + manufacturing and shipping time of 40 days).
Obviously if you have better terms, extending your cashflow becomes even more outrageous.
