Mostly everywhere senior developers are expected to self-manage and make difficult decisions on their own, unprompted, and just present working solutions to the business. It's okay to take time on this - solving it on your own, consulting literature, peers, etc. But looping in management into technical decision making might make you look like you can't make decisions on your own, or need micromanagement. Management, business and product care about things being done - not technical approaches or having to choose between multiple solutions.

If you're confident you can make mistake after mistake and no one will care unless everything comes crashing down - and even then there's a fair chance you can make it someone else's fault.

If you're merely very competent, taking time to research good solutions looks like indecision, not leadership, even if the results are far better.
