I can't vouch for its quality, but this has the full standard layout of those buttons (plus insert/delete). https://www.amazon.com/EPOMAKER-Mechanical-Swappable-Program...

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...
