STM programming - tools and libraries?

Question

Arduino

I use Arduino to flash an STM board via ST-LINK, my skills are basic, once a month I do something for a couple of hours as a hobby.
I came to the conclusion that I outgrew the arduino and I want something more, but there is not enough review material to choose from.
Tell me the current IDE and toolchain. I already managed to use Google, and I got the impression that in terms of the level of development of tools, this area was firmly stuck in the 20th century (Visual Studio 6 level).
Another concern is the question of Arduino libraries, including those for some devices, such as i2c screens: what to do with them?

Answer 1

1. Windows-way:
IDE - Keil uVision
Code generator for stm32fx - CubeMX for STM32 The
last program is just a great tool for a beginner. The Internet is full of tutorials for stm32f103 for example, or stm32f407.
2. Linux-way:
IDE - SW4STM32
Code generator for stm32fx - CubeMX for STM32
The code can be found on the github: i2c display stm32f*
Good luck.
