Yes, I use YNAB. So the various insurances - car but also house and contents, life, pet, if needed.
Any annual subscriptions like gym/amazon
You've mentioned dentist but might also want Opticians
You might want a separate eating out budget for tracking purposes, as that tends to be bigger than most people expect.
Are you thinking holidays would come out of savings, personal money or entertainment? You might want a separate category for them.
You have house maintenance and car maintenance but you might want a separate category for appliance replacement and tech replacement (what YNAB calls true expenses - you know at some point you will need to replace these things but not when).
You may want a category for bigger home improvements like a new kitchen.
If you want durable household items like new sheets/a new lamp/garden furniture - you might want a category for that.
And when you say savings, rule 1 is give every dolllar/pound a job, so ideally you'd be more specific- are you saving for x months' worth of income replacement, in case you lose your job, or towards a house deposit for kids, or retirement...?
Good luck with it. I've found it really helpful. There's a reddit ynab forum that can give more specific advice.
