There are many threads about pocket money/household running on MN if you care to search. Each answer is specific to the family/child, like on this thread, so perhaps not much help.
I never really did pocket money and I still don't.
. And I never tied it to household jobs - the reward for those is a functional house, fresh bedding, etc. In the household, DDs did jobs they could do and if there was any blowback, I pointed out that they could unload the d/w but only DH or I could drive them in the car to an activity.
For a while, in late primary/early secondary, DD1 was on £1/week and DD2 on 50p/week. Usually this was paid in arrears when one of us suddenly thought of it and thus I handed over a tenner and a fiver respectively or similar.
DH and I have always provided all essentials and many of their hearts' desires but sometimes deferred to birthdays or Christmas (e.g. new bike, laptop). Relatives gave generous gifts (e.g. smiggle backpacks, ugg boots) and often uncles gave a £20 note for birthdays or Christmas and DDs had that as 'pocket money'.
Aged 16, DD1 started at the local pub and has been raking it in ever since. DD2 has done some very lucrative cat-sitting. Nationwide has paid them £100 each at least twice.
TLDR:
People talk about 'teaching the value of money' but I think that lesson is easily learned. DC goes to shop with £5 and discovers how far it doesn't go. Teens want trendy clothes ...
A better lesson is relative costs: £300 for a handbag or 3 weeks' food shop; £50 for a tank of petrol or a takeaway; takeaway vs £50 of groceries.
More important is teaching about bank accounts: how they work and how to choose one and why and talking about how to plan for monthly costs (insurance, utilities, rent/mortgage).
Teach about ISAs and stocks & shares and pensions, interest rates, compound interest, dividends and the FTSE100 (not an under table game...)
