What would you say is the most "fun to work with" networking area?

I just finished my CCNA and I've been thinking about studying something new. I had fun working as an ISP NOC operator in the past, but it felt somewhat repetitive and i ended up burning out.

Cyber security and network automation seemed really interesting to me, but I think those areas would be even more repetitive in my daily work.

I do realize that most of the time the job as a networking engineer isn't really thrilling and fast-paced ; but I'm really curious about opinions from people who work in other areas. Thanks in advance!
