Don't worry about getting meat, fish and carbs into her - I mean, do include them in her diet, but at this point don't worry about the volume she gets. Her milk is taking care of most of her nutrition and will do for a good few months, so you can relax. Your HV really should be stressing this. The main thing with weaning is that you can cope! it's such a huge transition and I think gives many parents anxiety. Since you are mostly bf, you could add a multivitamin for her vitamin D and iron. We used Wellkid, but every other day, because the iron can contribute to constipation, which DD (now 20mo) tends toward too.
Apart from that, it sounds like she's eating brilliantly, so enjoy! I would say: no more baby rice, at all. If she liked it, give her proper porridge instead. Avoid sweet potato, it's like glue. Ditto banana, for some babies (sometimes it helps, so it is confusing!). Stewed fruit is brilliant for unblocking - plums, rhubarb, pear, and you can zap some tinned prunes / the juice into the mix. No need for it all to be purees, even if doing purees finger food is advised from 6mo, so fresh fruit too, whatever is ripe and juicy - strawberries, pear, mango, melon all fab.
