GIAC offers the highest standard of Cyber Security Certifications in the world. They are definitely more expensive, but if they are your target, I would recommend the training offered by SANS.
Offsec is an excellent resource for learning and validating offensive security skills. Kali Linux, possibly the most popular and widely recognized hacking toolkit was developed and is maintained by OffSec. Joseph Delgadillo is a Youtuber I like that has a good Kali Tutorial for beginners.
Other affordable options for getting your feet wet would be HackTheBox and/or TryHackMe.
