I've also really enjoyed my Keychron Q11. It only has 5 of those keys (I remapped them a bit because I find "end" more useful than "insert"), and have adjusted quite easily. Relative to the default, I've got Home/End where Ins/Del are, Del for PgUp, and PgUp/Dn where it has PgDn/Home. That was all painless to change in the mapping tool. https://www.keychron.com/products/keychron-q11-qmk-custom-me...
There used to be. I have a Microsoft keyboard[1] that works just fine using a PS2 <-> USB connector. Unfortunately I lost the PS2 <-> USB connector (which, IIRC, was an active converter, not a passive one) so I don't use it any more.
I use a standard mechanical keyboard with the standard US layout, and have not noticed any discomfort after 25 years or daily driving the standard layout.
[1] This particular one - first gen model: https://en.wikipedia.org/wiki/Microsoft_ergonomic_keyboards#... - although if you browse that entire page you'll see that there are newer models.
That's the usual way people use these smaller keyboards, and it's way superior in my opinion.
My non-QMK keyboard has a horrendous home+end location, which I only realized after I acquired the thing. I did not realize how much I rely on those keys in normal programming.
I have used such keyboards for many years and I have been content with them, even if a couple of years ago I have switched to a more compact completely split keyboard, without a separate digit pad (for 2 reasons, a closer position of the pointing device and easier transport in my luggage, due to its smaller total size, to be able to also use it instead of the non-ergonomic laptop keyboard).
You can achieve the same effect in a more convenient way by buying any of the many keyboards with separate parts for the hands, together with a separate numeric pad, which contains the third part of a classic 104/105-key keyboard.
The only remaining difference from the classic format is that on such keyboards the home-end and PgUp-PgDn key pairs are typically on the same vertical column at the right edge of the keyboard, instead of being side-by-side, but it is easy to become accustomed to this arrangement, which actually makes them easier to reach.
