Look at Ontario, Canada [1]. There’s an equal funding formula out of the general pool of funds for the province largely based on how many students are in your school board. The Toronto School Board (and I imagine other school boards too) then distribute their funds similarly [2]. School fundings isn’t tied to property taxes and it’s fundamentally weird to tie anything to property taxes as it gives back in services more to those areas that are already advantaged and creates skewed voting incentives.
I’m not saying that education in Canada was perfect, but I found the public school system to be decent enough with lots of opportunity to excel regardless and generally an equalizer (home dynamics it can’t correct for and is a huge problem). For example, I went to a well-regarded STEM magnate program that had objective entrance requirements that I had to travel to embedded within the public school. Out of two I got into, I ended up picking one closer because it was more convenient for my mom even though the other one I got into was a bit better regarded / and somehow had better funding (maybe more students but I suspect also outside funding drives / donations).
This travel problem repeats all the time with charter schools and is my main problem with the idea - when you’re wealthy travel is less of a problem (eg you have a very flexible work schedule).

What does matter is taxation on top 20% of population, and they do pay a lot of money on property taxes.
The average federal income tax is under 15%.
It would make a ridiculously large difference.
