Ok so if that's indeed what you are meaning then what's a small amount? I would imagine it would need to be a little progressive as well? I'm good with doing it this route and going slow but I also don't want to think everything is good and then add a fish and see something spike. The last tank was full live rock so that's easy but I've decided to go a slower less "crabby" route with dry rock and seed it with rubble where things have a harder time hiding. It's just hard to know what will maintain all the good stuff while the tank is empty and getting comfy.

All the nitrifying bacteria you need will come in on and in the live rock. It will spread onto the dry rock along with critters and algae such as coralline. It takes quite a while for dry rock to become as biologically effective as live rock. Nitrifying bacteria is easy and quick to establish, it is the denitrifying (anaerobic) bacteria that take time. That bacteria is what processes nitrate to (mainly) nitrogen gas. This can make a big difference when trying to control nitrate build up in your tank, but many people put too large a bioload in the aquarium for the rock to process all the nitrate so those people need to come up with other means like biopellets, macroalgae filters, etc.
A small amount of food to sustain the system would be, say, a 1cm square piece of flake food or a few pellets or a piece brine or mysis shrimp. If you add too much you will end up with more nitrate than the rock can deal with, so you really don't want to add very much. Using ammonia to cycle would amount to adding a large amount of food and you would end up with a large amount of resulting nitrate you would have to deal with.
Since you have a lot of time that could be spent cycling and "cooking" the live rock, you could purchase 100% live rock and give it a 20-30 minute 1:4 vinegar bath. This will make all hitchhiking critters abandon ship quite quickly in the bath, but won't be strong enough or long enough to do much harm to the nitrifying bacteria, or more importantly, the denitrifying bacteria. Just another approach to consider (I'm not a fan of dry rock haha).
Another thought, if your system is showing
any nitrate or phosphate it would be wise to keep the lights off. If there are nutrients in the water and nothing to eat algae you will end up with a nice "lawn" of hair algae or other nuisance algae.
