6 years including the grad program at your current firm? You need to move. You should be at Manager grade now - but I suspect the grad hire perception is still holding you back internally. You also need to be thinking where can you create the value proposition for your move into industry if you don't want to move beyond SM level - and that is unlikely to be delivery focused as you will want to position yourself in the strategic/executive function (at least at a functional or divisional level). So a move to a firm with a much stronger 'advisory' orientation would make sense. It would also allow you to effectively rebrand yourself internally - as a fast track SM in waiting, not someone looking for the means to sell a C4 promotion (current situation).Networks - differentiate between the networks which are actually peer relationships established over 6 years and networks established by being a go to person. You will build them at the new firm easily enough.As an SM at Big 4, unless you have aligned into a SME role, will carry a sales expectation. Not much difference there than where you are, and too many SMs plateau there as the opportunities to move up are often very limited - you will be in the poliltical queue behind others who have a longer tenure with the firm (including step up to SM). But as you want a jumping off point to industry that shouldn't matter.And then the old chestnut. Another company thinks you are worth 10K more than your current firm, and has already offered you the role (Manager) you want current (M4). you could go back and negotiate with your current firm - but why? They don't see you as someone they need to develop and reward to retain, its that too long here principle. 6 years in, you are losing traction and your light is fading fast there - don't expect a rise, or a promotion quickly when they will be wanting to retain and incentivise the new hire who stands on his/her outside options and makes it clear they are in demand with x and y firms where they also have networks and a reputation/track record. If they do fight to keep you, they will only do so with regrets and resentment.Go.
