Visa for a potential new role in the US

Hi. I'm a naturalized Canadian citizen in the US working on a TN Visa currently as a Consultant. Now I have a Corporate Development role being offered in a pharma company. What visa type could I work with this new co? I have BS in biology and MBA with plenty of Corp development experience. My preference would be a dual intent visa this time. Since the role may start in the middle of the year, is H1B still an option or do I need to wait for next year's lottery cycle? Can I apply for L1 visas without GC for now without being employed for a year outside of the US? Or TN is my only option at least to start with?
