Newbie to M&A's about to enter first internship - are there any 'top' sectors?

Hey guys,

New to M&A's here, will be interning at big4 CF M&A's and got the opportunity to likely choose my own groups of interest to specify in. Are there any specific sectors/industries that are potentially more valuable or optimal to learn in compared to others? Want to learn as much as possible and/or enhance my employability as much as possible.

I thank you for your time and attention.

Cheers!
