I’m currently looking to add more variety to my feedings because as they say variety is important in reef tanks.
Below I’ve attached pictures of what I feed and what I soak my food in, usually soak for 20 minutes and freeze the rest for the next day.
Your variety looks awesome to me, and is about what I do when I can get my hands on stuff, plus or minus a couple.
I don't like to feed TOO many brine shrimp, even the supposedly 'fortified' ones. I reserve those for the most picky eaters.
Hikari makes others foods, so have a look at their website to see if there are other packages you may like your LFS to stock.
Lots of Hikari in my freezer, and some PE. I used to use the large slabs of PE, but switched to the cubes for ease of mixing with my other cubes.
I do as a couple others have mentioned/pictured use;
I have silicon cube trays and make my own mixes. Saves thawing/refreezing multiple times.
I thaw all the tinfoil cubes just enough to mix (but not enough to fully thaw), then spread in the trays. After an overnight freezing the trays covered in wax paper, I break them out of the silicon trays and vacuum pack them in batches with a Foodsaver. I use them up in about 3 months, but have made batches that lasted over 6 months without issues. Just be sure to remove as much air as possible to avoid freezer burn/crystalizing.
I only keep about a week's worth in a covered dish in the freezer, and only a day's worth in the fridge (if there are leftovers). I never re-freeze any that has been previously frozen, aside from re-freezing the cubes after mixing.
The only thing I see in your stockpile I wouldn't use regularly is the Garlic.
I only use it for finicky fish, and only during QT.
Once fish are added to the DT I stopped using garlic additives as there's been some recent chatter about garlic causing liver issues with Marine Fish.
