If you truly want to be good in cybersecurity and not just the “first level support for the security department where you simply follow a script”, you need a breadth of knowledge all the way down to the fundamental way computers work. For languages you’ll have to know ones most people don’t learn anymore like C and assembler (most of Linux and tons of the Linux ecosystem are in C). Then be pretty good at a lot of other ones such as python, bash, SQL, javascript, etc. and will need to understand how an OS works at it lowest levels.
I roll my eyes at the cybersecurity certificates you can get in 6 or 9 months.
IMO you have to start with a Computer Science degree. Just my $.02.
