It's looks are not everyones cup of tea, but apart from that, the Toyota C-HR hybrid ticks all your boxes. The hybrid only comes as an auto, and going by what I have read about them, they are refined (unless you are going flat out) and ride well. They are spacious, though rear passengers may feel a little claustrophobic due to the small windows. Not 100% sure which spec gets what as standard, but looking on Autotrader, it appears the basic Icon spec doesn't have heated seats, but Design and Dynamic and Excel trim do. £20k is enough to get into a 2018/2019 example such as this one; 202107145011793

Re the Mini, the clubman shares its mechanical parts with the BMW X1, but personally I wouldn't have either. Never really looked into the reliability of Mini's (any of them, as they do absolutely nothing for me). But given the reliability of BMW's in general is is not as good as you might expect, I'd expect a car which uses the same platform/drivetrain not to be any different. Also, don't expect a comfortable ride from a Clubman, especially versions with larger wheels (as 90% or more appear to).

Whatever you go for, get a model that has higher profile tyres, because rural roads (from holidaying in the West Country for nearly 20 years now) are not exactly smooth, and they are obviously better on road comfort, put less strain on suspension parts and are less likely to lead ot wheel damage.

Plus they give better mpg and grip better (for the same tyre) in snow or muddy roads as they are normally not so wide. And far cheaper to replace.

(as an example) For the Mazda CX-3 (I own a Mazda3 and have test drive a CX-3), most models for sale tend to be Sport models shod on 18in alloys and low profile tyres. The better value SE-L (Nav) and SE models come shod on softer riding (still fine handling) higher profile 16in rims and tyres.

Admitedly the CX-3, based on the Mazda2 floorpan, is not a particualrly large car, but it might do.

You might want to onsider a Suzuki Vitara, similarish size to most on the list (perhaps a little larger).

Of any car you think about that gets onto your 'final 5' list, check it out for interior comfort.driving position/space for you, passengers and boot space (I always bring things to check its big enough - e.g. suitcases, golf bag, etc) and get a long test drive on a wide variety of roads, especially ones of the type/condition you'll use to get the best indication to whether its a good fit for you.

Don't go on looks if the car isn't right on other crutial fronts like comfort incuding driving position), space and handling/drive.

Make sure the dealership backup is good - some makes don't have that many (well-regarded) dealerships in more rural areas, and with some (sadly, as with Mazda, IMHO) it can be a bit of a lottery where a dealership in your area is good for post-sales maintenance work. I was lucky with mine, others haven't been.

If you're buying a car outside of its warranty period and you have a local indie garage that looks after many makes (and can for those on your final list) and has a good reputation you trust, then that can make things a bit easier. Bear in mind newer cars have a good deal more tech nowadays and some smaller indie garages might not have the required facilities to carry out all aspects of maintenance.
