Not a lot of options in the physical keyboard space. At the moment, you can wait for the Minimal Phone though there’s a good chance it’ll never ship.

There’s no physical keyboard, but the LightPhone III is coming out in the winter. Having used the LightPhone II for over a year, I can say that these people have really thought out the dumb phone experience. It’s a premium product for sure. My biggest complaints with the LPII involved the slow response of the eink display, and the LPIII should fix that by switching to amoled.

You can look into the Unihertz Titan series (I haven't tried them myself tho)
