Сreating a web interface for accessing the database

Good day. I hope for your help.

I will soon have a thesis defense and i need to create a web interface to access the database.

I compared all the main current products and i cant decide what is missing in this area.

There are lightweight (Adminer, phpLiteAdmin), there are for certain databases (PosgreSQL - pgAdmin 4, MySQL/MariaDB - phpMyAdmin) and so on...

My questions:
1) What do you think is missing in these products and i could implement it in my project? I thought about security and focus on it, as well as the simplicity of the UI.
2) What tools are best to use?
3) Which database to focus on or do under any like Adminer?
