I went through the same thought process several years ago. I ended up not getting my MBA and it was the right decision for me. I am now retired (FIRE @48) and I do not believe my lack of an MBA has impeded me in any way. Partly because so much information is available online, I can acquire any knowledge I need on an as needed basis.
The Executive MBA at the University of Utah (UofU) which I was considering was rather expensive and would not have changed my income or career path. When I was looking at the program the cost was roughly $60,000, a quick review of their website, shows that it is now $82,000. In my situation that would have been a complete waste. That money went into my retirement and allowed me to retire early.
Near the end of my career my company began requiring a masters degree for management positions, however, those already in management were grandfathered for five years. I was in the process of downsizing my career so it made no difference to me either way. However, my co-workers began getting their masters to meet this requirement.
Many of them went to Western Governors University for their degrees. It is an online self-paced program. The quicker you finish the degree the cheaper it is and most of my coworkers completed their degrees in two terms. At a cost of $3250 per term for a total cost of less than $7k, they paid a fraction of what an executive UofU MBA would have cost, they met the company masters degree requirement and learned a lot in the process.
In summary, it comes down to your motivations and requirements. If you are simply seeking the knowledge there are cheaper options available that might meet your needs.
