Need advice on adding AMEX gold to current card lineup.

Current lineup:

Sapphire Reserve (used to pay rent, and dining). The small fee to pay rent with a card is worth it for me. I travel several times a year (very thankful to do so). This card makes sense for me.

Venture X- have it for the additional travel credit, and to have another travel card. Use it monthly (a few hundred) to keep activity on it.

Savor- got it as my previous Savor was bucketed. Cancelled the bucketed card. $200 SUB and the $100 travel credit for a zero fee card is hard to pass up. Use this card for groceries, due to the great multiplier.

I would like to add the AMEX gold card.

Why?

To have another card with another lender, and a card that is a charge card vs. only credit cards (diversify, so to speak).

Great multipliers on groceries, and dining.

I spend roughly $800 on groceries and dining a month.

I would use about half of the card credits organically.

I would easily offset the AF, and be in “profit” about $1k yearly with the credits and points earned with monthly spend.

I have been pre-approved with the 100k SUB (I’m surprised at the SUB). A big year 1 value.

Salary: $130k

FICO 8: 730

I never carry a balance.
