I need to lengthen some old wiring in order to make all the wires of a
3-way switch come together in a recessed lighting box that I am installing
in a first floor ceiling (no insulation).

In doing some web research, I see that splices can be done, but they must
be done in a junction box, and must be accessible.

It is the second part that is confusing me. How can I make the junction
box accessible when I just need to lengthen the wire by about a foot in
the ceiling of a finished area? It wouldn't be a big deal to remove the
light fixture, but "accessible" to me means the box is visible or in some
access door.

Thanks.

The junction box of most recessed fixtures is designed for feed through
splices. Although it is essentially buried in the ceiling, it is legal
because it's accessible by simply removing part of the fixture . In you
situation, you may have too many conductors in the box
