Your networking strategy can depend on your specific objectives, but it's generally beneficial to have a diverse network, both in terms of geography and role.
Networking with partners, regardless of their location, can be very advantageous. Partners are often influential and may have broad connections within the firm, which could help you learn about different opportunities or gain different perspectives. Furthermore, a recommendation from a partner can carry a lot of weight in the hiring process.
However, networking with consultants at the manager level in your city can also be beneficial, especially if you're specifically interested in working in that location. They can provide a closer look at the work culture, the types of projects commonly handled in that office, and the specifics of working and living in your city. Their insights can be incredibly valuable as they're likely more involved in the day-to-day work and might have more time to mentor or guide you.
In summary, there isn't a one-size-fits-all answer to your question. It could be beneficial to continue networking with partners outside your city while also building relationships with consultants in your local office. This way, you can benefit from the partners' broad connections and influence, as well as the local insights from consultants in your city.
