Decaf is very nice as an espresso.
You basically have Svart for brews/pour overs (assuming it is fine to grind medium light / light roasts) and Jx for occasional espressos
If you want an all-in-one better option, then you are going to require a single dose grinder, which is a better option for espresso, brews/pour overs, using more than one type of beans, etc.
Of the single doser, I would still consider (a) Oro (£500) mainly for espresso, (b) Niche (£500) the great all rounder and the best IMO and the competitively priced and © Solo (£400). As far as the latter is concerned, some are happy, some aren’t and many have modded it to suit their convenience. I am sure we have some Solo users here, who would be able to chip-in with their views.
There is one Lagom Mini, which I think is still not out. I have no clue what it is and how it would be.
The final choice is buying a used Mazzer —- there is one in our classified—- and modify it for a single dose. @Cuprajake has a modified Mazzer and uses the SSP burrs for single dosing. He will be able to advise you on this further.
