Best resource for DFIR/Blue teaming

Hi everyone. I am eJPT certified and been doing tryhackme for a year now. I want to move towards blue side, especially forensics and incident response. What i wanna ask is what is best resource/website to learn dfir/soc etc Are elearn security forensics and incident response courses and certs valuable? Or should i stick with tryhackme (it has less content regarding blue teaming) I have also heard of securityblueteam so is the investment there invaluable? Thanks
