It is not at all as "bad" as for non-EU nationals. There are three restrictions. The quota is one of them (independent of the non-EU limits).

Local workers are given priority. In order to hire an EU-10 citizen, the employer must have been unable to hire a person integrated in the Swiss job market (Swiss or a foreigner). This is a much weaker condition compared to that applied to non-EU people, still it is an obstacle.

The last obstacle is a check of salary and working conditions.

Marriage is likely to solve everything. If you've got a B, the wife gets a B and no restrictions can be applied.

EU-10 wives on a "dependent" L are subject to salary & working conditions checks, no local preference or quotas apply.

Given the OP has got a B permit, they would be fine...
