You've gone about it the right way by fixing the environment first, but
don't forget - the bleach doesn't "kill" the mould, it merely bleaches it
white/whiter. Better to use a borax based solution, or one of the EPA
approved formulas designed to actually kill the mould.

"Killing" or "removing" or "cleaning"? Bleach is a good, but strong and
hazardous, product to use to clean up mold growth. Without correcting
the conditions that allow mold growth, using bleach is kind of like
running a dehumidifier outdoors when it is raining .. the dehumidifier
is doing what it is supposed to do (removing moisture from the air) but,
of course, not changing the basic condition. Mold spores are everywhere
(like the rain outdoors) and will grow where/when conditions are right.
High humidity helps them a lot.

OP said he did a lot to correct the humidity. Wise move. Bleach is a
good cleaner, but not for wood or metal surfaces, and tough to use
without proper ventillation.

"Toxic" mold might depend a bit on who is living with it .. plain old
household dust is tough on people with allergies or asthma. Basic
housekeeping practices help .. don't accumulate stuff that is housing or
food for pests, vacuum thoroughly and regularly, sunlight and
ventillation, repair/replace water damaged wood and wallboard.
