I would start with the free ISC2 CC certification.
ISC2 provides both the online self-paced training and the exam vouchers to you free of charge.
From there, you’d want to look into CompTIA for their Network+ and Security+ certifications.
You said you are leaning towards Cloud Security. CompTIA also has the Cloud+ certification.

Certification bodies such as ISC2, CompTIA, ISACA, GIAC, etc. provide official training for their own certification exams themselves.
If you are looking for additional third-party training providers for your self-paced online studies, you can also look into the following:
CBTNuggets
Cybrary
HowToNetwork
LinkedIn Learning
O'Reilly
Pluralsight
ProfessorMesser
Skillsoft
Udemy
For free webinars, sign up with https://www.brighttalk.com
For online labs, give TryHackMe a try.
Join Reddit communities such as ISC2, CompTIA, etc.
And join Discord groups such as CyberSecStation (formerly Certification Station).
I believe you may also qualify to join the ACM because of your work background.
Best of luck!
@n7admin I would echo what @Spirnia said.
I would especially encourage you to look at the different kind of careers within cybersecurity/infosec. Cloud is but one kind of job you can do. And that sometimes this may change as your career changes. I went from being a system administrator to being a security administrator to being a security assessor/consultant to being a CISO& DPO. If you had asked if I planned on being a CISO 5-10 years ago I would have laughed.
I would encourage you to look for local groups to get involved in to meet and network with your peers. This is a great way to find jobs. Look for local chapters of ISSA, ISACA, ISC2, Infragard (if in the US), OWASP, CSA, Defcon, etc. Look for local security conferences organized by these groups as well as local BSides. Many of these conferences, especially BSides, will often have career tracks aimed at job seekers.
