Which DBMS to choose for a small company?

Question

SQL

Hello. I know that this question has been asked many times, but I myself could not decide for sure.
Essence of the question.
I need to make a program for a garment factory. She must keep all records of the plant (the arrival of fabrics, workers, accessories, expenses, shipments, and much more).
At the same time, 20 people will work in the program. (And even not at the same time).
But there are 4 computers in which seamstresses will constantly and simultaneously drive in their operations.
I don’t know how big the database should be, I have no experience. We now have an accounting program and it has a database for 2-3 years 150mb. There are 160 seamstresses at the factory so far and there will be more. every day they perform about 10 operations. And every month the salary will be considered.
I had experience with MYSQL (wrote an online store on it) but I'm not sure if it can handle it. I chose between MYSQL and PostgreSQL. I will write in python + PyQt. I am not a programmer, but self-taught. I want to start trying and if it works out, then make this program.
This is my first time asking a question on a toaster. Sorry if something is wrong.
ps
We use MySQL. No problems are observed.
