For L2 Network engineer with 8+ yr exp, what domain/skills should i pursue for maximizing salary?

I have experience in R&S (done CCNA), Security (ASA & palo alto), ansible automation. There is no scope to learn newer technogies other than above in current project.

I am listing below all the technologies that various persons have advised me to learn at different times and so many suggestions are totally confusing me. I have no affinity/passion for 1 stream over another stream in networking. My objective for wanting to learn 1 of below skills is to score more interview calls/negotiate higher salary. Assuming i have time to study only 2 of below technologies in next 1 yr, which can i pursue or any other suggestion also welcome?

CCNP R&S

Python

F5 load balancer

Nexus
