LPT Request: Tricks and techniques in handling yourself better/effectively in group discussions/work meetings so you are heard/respected and win over others.

I just came out of a work meeting which I feel was a failure for all involved even though the main 2 alpha males did most of the speaking and got their way/circle-jerked.

It was really frustrating as I am by far the most knowledgeable/skilled amongst the participants (dont mean to boast, Its just my specialty that I have always taken the lead on and worked hard skill upl).

Now the rest of the 'full timers' who I can only describe as 'old wood': they know a fair bit about all the stuff at the company, but by no means experts (thus why they get contractors in). I expected a couple of them knew enough to contribute and play along with what I had planned and help detail a task list for actioning, but I didnt expect them to simply over-rule me at every point and leave me unable to get a word in, and comfortably winning over the management the way they did.

Ideally I was hoping for them to hear me out and accept my offer/volunteer to oversee and do the work myself (actually be quite easy/straight forward for what I had planned; but they decided on something way more convoluted and unfeasible).

In the end I was only hoping to offer some valuable services which I know they are in very real need of, but ultimately half way through the meeting I switched off altogether and stopped caring and let them go about it how they will always were going to and otherwise falls outside my control.

And I'm not so bothered about not getting my way or owning the project the way I'd hoped, I'm more of the realization that I obviously lack some character traits/skills that are required to influence/persuade my counterparts the way I'd ultimately wish I could do so- without being a bully/douche/loud alpha or perceived as full of myself.

So in terms of handling myself better in the future; has anyone had success in adopting their own set of rules/tricks that they have lived by to succeed/negotiate a better outcome for themselves in work meetings or similar?

TL;DR Teach me some tricks/tactics to win over others and/or get your way in a meeting against other competing mere mortals without being a jerk or upsetting others too much!.
