I want to mount this piece of plywood in such a way that it is reasonable removable.

I first need to true up the edges of the wood and that is difficult because of it's small size.

I have a table saw, circular saw, and reciprocating saw.

I would like to avoid the table saw because of its weight and bulk.

How can I true up the wood?

With the table saw. No other tool you own will do as good a job, as
easily , quickly, and safely, as the table saw with a good fence and a
good miter slide. A sled would be even better, but not a REQUIREMENT

I have no requirement for perfection.

I wonder how craftsman did it before they made table saws?

If you don't need "perfection" use it as it is. Before table says
they had huge circular saws run off a line-shaft. Before that they had
"pit saws" - and craftesmen who knew how to do things precisely with
hand saws and planes.

Get yourself a set of japanese saws, a square and a pencil.
