What toolkit to choose?

Question

PostgreSQL

Hello.
I'm not exactly new to programming, but just started getting into web development. I want to create a service as an experiment to gain experience. But I don't know which instrument to choose.
There is a site. It has a map on it. The user logs in, the JavaScript API requests the location and creates a map, pulling out labels from the database that are close to the user in coordinates. There is a button, it adds a label with a name, description, coordinates to the database. But I have no idea how to implement it.
I plan to use PostgreSQL. How to pull data from the database (sorry for the tautology), because Maps need a representation in JSON format?
In general, the use of Python, Django, PostgreSQL was originally conceived. But they say that in PHP, MySQL will be easier. I am already familiar with Python, I know basic PHP.
An important factor is the speed of development, as little time as possible should pass from a stupid idea to the very trial implementation.
Thanks in advance to all who respond.

I won’t tell you what you need for maps, but JSON and PostgreSQL / MySQL have been around for a long time / recently
Postgres periodically boasts of superiority over Mongo in this matter
from scratch, in my opinion, it will be the same - I don’t see the advantages of PHP frameworks over harnessing to Django, except perhaps , more Russian-language materials, and even then ...
