Note that a Schengen C visa does not allow you to work remote from those Schengen states. A bit simplified, you can visit on a C visa to talk about what work you need to do, but not to actually perform it. For that, you would need a national visa with a work permit, which are considerably harder to get.

As a general rule, travel plans (when, for how long and for how many journeys) determine the type and period of validity for a Schengen visitor (‘C’) visa.
Long term multiple-entry C visas valid for 1, 2, or 5 years are not usually given unless the applicant has previously been issued with a Schengen visa (not an airport transit visa) 3 times, or has previously held a long term multiple-entry visa.
If you’ve never had a Schengen visa before AFAIK there is nothing to stop you from applying to any country, but your application will be refused as you do not meet the eligibility criteria.
