Ok so I did LOADS of reading on indoor/outdoor before I got the Kitten.
The cats we had when I was a child were very much outdoor cats and hardly came in. They were kittens from a farm cat and were beautiful and strong and amazing hunters and very clever but not super good pets TBH because they were never bloody in. We had a huge garden backing onto fields and woods and they had massive hunting territory.
Now I live in a 3 bed semi with small garden, in London, busy roads. I was going to keep the Kitten as an indoor cat but but actually have gone down the cat proof garden root and I am so happy I have done so.
Having access to the garden extends his 'territory' by about 1/3 and there are lots of exciting things to look at (birds, squirrels) and things to chase (fly, leaves) and he loves a good dig in the flower beds.
Cats need to be able to exhibit natural behaviors - hunting/stalking, climbing, scratching, grooming
If you have indoor cats you need to make more effort to enrich their environment. Cat trees, different scratch pads/posts, high places to hang out, more toys, puzzle toys, more time from you to play with them, grow cat grass to nibble etc.
Indoor cats will be more bonded to you and better 'pets' because they will be around not out killing rabbits (yes, really, I'm looking at you Tabby).
Not all cats will be happy indoors tho, so I think you do need to be led by them.
If you are prepared to put the effort into making their home environment good I don't see why you can't try them as indoor cats.
