I gather that the commercially-sold wormeries are designed to produce
liquid fertilizer, and not much else. Is that correct?

No this is no true.

The worms eat the vegetation and produce the "compost".

-------------------------------------------------------------------------------------------------------------------
Worms can eat up to half their own body weight every day and can double their
population every 60-90 days. If you start your wormery with 1 kilo of mature
worms they will consume up to 500g of food waste per day*. After a few months
you should have double your population and you can feed them more. As you
become familiar with your system you will learn their rate of food consumption.
* This is dependant on the time of year, and how long your wormery has been
running

as an approximate guideline a 75 litre wormery should be able to manage 2 - 3
kilos of food per week.

This is dependant on the season and how long your wormery has been running for

You appear to have confused the amount worms consume, with the amount of
compost worms produce. IME the amount of compost produced is so minimal
it's not worth the trouble. The largest usable product of wormeries is the
liquid waste , a good liquid fertiliser but no better than effortless
ones such as nettle and comfrey tea.

IMO (and IME of both) any gardener with enough room (and waste) for a
compost heap will get a much better worm-return by introducing a colony of
brandlings to it. You only need to do it once and never have to do any
worm care ; and if you know someone with a successful compost heap they
can easily supply you with a handful of brandlings.
