If I'm not using my flex 20 tix I usually sit above the champions club. Quite often you can find a great deal on StubHub or Vivid Seats a few days before, especially for a weekday 12:15 game.. I've paid as low as $22 (included fees) to sit in the front row of 111.
There really aren't any bad seats, although you lose some OF view in parts of the upper deck in the OF, especially if you're in CF. I'm limited myself in where I sit as my eyes aren't that good these days.
I generally don't go out before of after, but The Loon has great food, and Cowboy Jack's has $2 beers, or at least they did before the pandemic.
