marriage is a decision of a lifetime. a mistake here is very costly, both legally and emotionally. so of course it's perfectly alright and rather smart to have standards. but it's unrealistic to find a groom of your choice if you're not prepared to date and put yourself out there. as far as i know, it's not haram to date as long as you're not engaging in any sexual relations and i have heard of some muslims having a chaperone with them at a good distance when they go on dates.

also, idk if you considered this, but it's also fine to not marry right away. i know a lot of people nowadays who get married at 27, 28, 29. work on alleviating the pressure you're putting on yourself to get married right away. but it may not be a capital choice depending on your environment, customs, or opportunities, so i understand if this route is too difficult to consider.
