By needing a powered tailgate your look at mid range up models, which of course increases the advanced payment.
The Suzuki Swace estate, I don’t believe has a powered tailgate and I don’t believe the Corolla does either, plus its more expensive than the Swace.
The 2025 MG HS Trophy auto £1299 AP get decent reviews and what equipment it hasn’t got isn’t worth having! Boot space is 507l/1484l with the seats folded, not to disimilar from the Swace. The Omoda 5 is cheaper and gets a decent amount of kit but, less refined than the HS.
Given your on your own a smaller vehicle my benefit with the rear seats folded.
Hoist wise, something like the Autochair LM 40-80kg would be more than adequate.
