Misconception: B2B is about selling to businesses and so the end UI/UX is not as important.
In reality, the end user is always a person and there are people that are looking at easy products to use and making the decision to buy from you. The easier your product makes their job, the more inclined they will be to get your products. This applies for products as well as product operations - easy on-boarding, solid customer support and focus on data and reporting as possible.
For me the biggest differentiator is having a growth mindset. This doesn't just mean they want to make an impact and improve as a PM. For me it comes down to three things:
My biggest frustration is that I let people down. Currently, I work with teams of 50+ people, which means I need to be available all the time. The more senior as a PM you become the more folks you need to work with. Time becomes the most valuable thing and I'm still learning how to manage it effectively.
Being patient when I would like to be impatient. Product management is deeply humbling in that good things often take time. I like to say that I am "tactically impatient, strategically patient" - as in, obsess over small details and steps every day and treat them with urgency, but know that things take time to build, and big goals take time to achieve. But, being honest, this comes with a hidden frustration for me, an inherently impatient person :-)
If you enjoy Product, a typical path is either to become a people manager, remain IC, or quit to start your own thing. In big companies like Salesforce, there are plenty of Director level individual contributors (ICs), so if you don't want to manage other PMs, you are better off in a bigger company where you can focus on one specific product.
I see a lot of PMs succeeding in startegy and operaitons roles. I have been tapped a few times for COO / Strategy & BizOps / Chief of Staff types roles because of the product background. Your ability to understand and connect the dots across business and customers, as well as manage stakeholders, is super valuable in all of those roles.
