How can you tell the median benefit a typical person gets from taxation?

There's tons and tons and tons of resources on how much a person spends on taxation, but I can't find many (admittedly didn't try that hard) on what benefits the median citizen gets.

Actual country doesn't matter, I just wanna know some sources to base on.

What I mean via example is, grab two countries, A and B, and while A has more tax revenue than B they also have more population so their relative tax spending per capita is the same… however the people in country A is absolutely disturbed by their lack of services (low benefit) while country B is relatively happy with their services.

things might get complicated tho with country C where people get less services but their reported happiness with those services is higher… so IDK

…

BASICALLY – I wanna know how to calculate or estimate the median/average/whatever benefit a person gets from their taxes as a ratio of what they spend; and since services cost different amounts in different countries the only metric I can think of is customer/citizen satisfaction.
