To get started, why not use what you have and bend the leads to
convert them to surface-mount parts?

It'll save you lots of holes,

It will certainly do. I'll try it out with the next simple
design, maybe a dozen or so components.
except for the inevitable jumpers you'll
need on what was the component side of the board if you use
single
sided board and can't work out those pesky crossovers.
I have certain self-imposed rules while designing a PCB, one of
which is to use as few jumpers as possible. Having dozens of them
on a single board somehow seems clumsy to me.

And I really hate "those pesky crossovers" as you call them.
Working on an existing product during a fault-finding session
and/or when trying to improvise replacements with locally
available parts, all without any kind of manual, it's often
necessary to trace the circuit and reverse engineer it. It's easy
to develop an intense dislike for those crossovers, especially
when they occur every few millimeters.

Thanks for the suggestion. I work a lot with members of the
medical profession including dental surgeons, but the idea of
using a dental bit never occurred to me. If it's good enough to
drill teeth, it should be good enough to drill FR4.

Follow-up: Just finished calling a friend who runs a dental
clinic with his wife who's also a dental surgeon. He happened to
be away in Delhi but he said that he has a good stock of diamond
and carbide burs. He told me to go to his clinic tomorrow and
take whatever I need.

You want a bur with a ball shaped tip for drilling holes. The tips
come in a variety of shapes, but AFAIK ball shape is best.
