Here’s ours. We make about $100k after taxes. No kids yet.

Rent 20%
Cars/Gas/Ins 4% (two used cars, about 12k miles a year)
Utils 5%
Food 9% (6% eating in + 3% eating out)
Pets 2%
Health 3%
Fun & Vacations 11%
Down Payment Fund 20%
Roths 10%
401k 16% (+4% match)

After carefully tracking dollars in our monthly Food/Pets/Health/Fun budgets and having it be a constant irritant, we recently switched to a new system that’s working well:

Category 1: Groceries, Cars, Pets, Health. This costs whatever it does, and we don’t skimp.
Category 2: Eating out, housewares, fun, spending money. This we aim for $600-700 a month (based on averaging our old painful budget data)
Category 3: Vacations & major house improvements, which are budgeted separately.
