I'm already really excited about including DS2 in family meals and he's not even born yet 
I loved BLW with DS1, was one of my favourite things ever. They really don't choke, basically if they can hold it and get it to their mouth themselves it's probably fine - raw apple can be a bit of a problem and anything largeish and round like cherry tomatoes, grapes, sausage but you just cut them into a different shape. It's amazing to see them handling and exploring all kinds of foods. Omelette and fish are brilliant things to give a baby.
Unfortunately at 9 he's a fussy bugger
but since this behaviour (take all foods, section off favourite 10%, declare all others poison, recalibrate any time a new favourite food comes up, rendering 90% of old favourites discarded) is also replicated with clothing, underwear, leisure activities, TV programmes, and friends I'm not sure that feeding him a varied diet as a baby did him any harm.
I think it's really beneficial to them not to hold back actually. Why not let them try spice? They will soon let you know if they don't like it. I might be worried about hurting their mouths if I went with something too strong in spice too soon but I'd start off with milder things and work up, or something like piri piri tends to taste stronger at the edges so I might break it up and give pieces from the inside to get some of the flavour. Things like chilli con carne can be moderated with a spoonful of sour cream or natural yoghurt. Salt content must be carefully watched before 1yo but they eat such small amounts I did not find it very difficult to stay under the limit simply by avoiding too many processed foods.
I didn't choose to puree but if I was going to then I would either mash things with a fork, a mixture of what we were eating, or I'd save a selection of the day/meal before and blend it up ready for the next meal. Probably with some spares in case we had something like takeaway or beige tea or frozen pizza or whatever. I'm not going to worry overly about jarred sauces though I will have to go back to reading the labels and I might be more careful about what I buy in the supermarket. But for example from a random jar of tomato and basil sauce from the Tesco website: 0.83g salt in 100g (which is a bit more than 1/4 of the jar). Even if I'd used the whole jar in the pasta for all of us, I wouldn't expect a baby under a year to have even half of an adult portion, so that's maybe 0.3g max. I wouldn't have added salt to the pasta when cooking and I wouldn't add cheese, bacon, olives or sausage to the baby's portion if I was worried about the sauce. OTOH if I'd used a can of chopped tomatoes then I might feel OK about letting them have a few bits of the saltier ingredients.
I have heard about certain fruits being discouraged in other countries but they aren't mentioned on the NHS weaning guidelines so I have never worried about them. The only things I stayed aware of was salt levels, honey and choking hazards as mentioned before.
