I need 30 amps in a single room to run vegetable grow lighting. How to accomplish?

Since you've got conduit, and since most lights are not designed to be directly on 30A circuits (normally in the US designed for 15A or 20A circuits), run two 15A or 20A circuits through that conduit ...

What is / was the purpose of these old openable-cover junction boxes?

They appear to have been fuse boxes, which goes with the openable cover and diagram peeking out from under the paint. Presumably they were decommissioned as fuse boxes but retained as junction boxes.

How do you mount conduit to a wall so that it stands off a standard box distance?

If you don't want to get a conduit bender, you can use conduit hanger clamps like the one shown below from Home Depot. The clamp fastens to the wall and holds the conduit away from the wall.
