We'd recommend the Volkswagen T-Cross out of your shortlist. All models come with a sliding rear bench, which lets you prioritise space in the boot or for rear passengers, while most also come with an adjustable boot floor. This means you can virtually eliminate the usual boot lip – making loading bulky items easier. The Skoda Kamiq is a good alternative. It's very similar to the T-Cross, although it doesn't have the sliding bench.
