Many large companies now have in-house consulting functions. This is a common move for people with three years experience. If not as part of an official in-house consulting team, there are other project roles for someone in your position.
In these roles experience in the industry is normally valued highly - so some consistency of industry experience over your three years would benefit you, plus help you to narrow the field.
That said, don't be constrained by the 'in house change' types of roles. The world's your oyster at this point in your career. Also don't worry about the money (too much), some of the jobs with the best long term prospects for money/happiness pay nothing at the bottom end. Plus, almost all jobs outside of consulting will see slower pay growth over the next 3-4 years. You may even need to take a pay cut if you change direction. But if you're clear with what you want to do you'll catch up again soon enough.
Commercial manager typically means performance management accountant. In case you weren't aware. An obtainable job but probably results in a career in the finance function.
If you're set on leaving consulting, then I think you're doing the right thing leaving after 3 years.
If I may add from your admittedly brief post, it sounds like you need a bit of direction and clarity on what you're after. By all means find some recruiters on linkedin and sit down with them. But they'll probably only tell you the jobs they have. You may need to think a bit more about the type of career you want first for those conversations to be useful.
