I agree with one of the above posters that a HV who is recommending weaning for a non-medical reason is just rubbish and the NHS specifically recommends not weaning until 6 months (unless there is a true medical reason). If you want to do BLW, just wait until closer to 6 months. You don't have to wait until 6 months on the dot and if you want to start a few days earlier there's no harm, as long as your baby can sit up safely to eat. They mostly don't eat much for the first month or so anyway. It's just touching food and practicing bringing it to the month. But all babies do better at eating once they've lost the tongue thrust reflux, which tends to happen around 6 months. It doesn't mean they can't safely eat before than, but they may be more likely to gag on finger foods in really awful dramatic ways until that reflex goes away. That tends to put some people off BLW weaning because they freak out and think their baby is going to choke. There's no added benefit to starting early and it might be a more relaxed and enjoyable experience for you if you give him a bit more time to grow and develop before diving into finger foods. There's nothing 'wrong' with spoonfeeding, but there's no point to spoonfeeding for two weeks and then changing the game entirely and switching to BLW.
That being said, weaning, even with BLW, is a lot of work to start and it takes up time and you'll spend time preparing foods and planning meals that you could spend doing other fun things with your baby. This is the case even when you are doing BLW and feeding baby mostly what you're eating. You still have to adjust things for sugar/salt content, sometimes meaning you have to cook two lots of things (one for you and one for baby), and you'll spend more time cooking from scratch, if you're someone who tends to have a ready meal or takeaway a couple nights a week. It's just extra work and extra planning. BLW is wonderful. But if you have an extra month just to relax and not worry about making healthy meals on top of all the other things you already do as a mum, take it and enjoy it. Weaning will come around soon enough and you'll realise there was no need to rush it.
