From what I've read, the "Toxic" black mold had spores that are harmful

Absolutely.

Tearing out the flooring in my bedroom will give me access to bad
floor joists that need replaced and will also give me easier access
to the crawl space for putting down a moisture barrier, sealing
vents, and installing a sump pump and dehumidifier.

Just an exhaust fan and better drainage would probably help a lot.

In researching this there are some ventilation systems that use sensors with
fans to ventilate when the outside air would help dry the crawlspace and
they close off when the outside air would bring more moisture into the crawl
space.

There is mold on the floor at the top of the crawl space, no where for
moisture to come from except from the air condensing moisture on the cool
crawlspace. I guess hot moist air entering a cool crawl space brings
moisture in.
