You should consider which ingredients, materials and recipes are available too. In the decision, you can prepare something already known by you or learn to cook new food. If you are so confident and you have conditions to do that, you can create a new kind of food related to his culture or native country, demonstrating more originality. Also, if he likes to cook, you can invite him to help you when convenient to both. The couple may have fun cooking together, sharing ideas possibly.
Some men love to cook and want to take care of the kitchen too. On the other hand, some guys do not enjoy that. Generally, they think that it is essential the wife to cook, more important than love in some cases. While that, other men do not give big attention if the wife cook well or not, for example, some busy men that prefer dinner out or to eat at restaurant. So, cooking has great importance for some men, while for others, not that much. Anyway, good cooking skills are appreciable in general, being a quality of the person. That quality associated with other things of the person may conquer someone. Mistakes are possible when cooking, but you may learn more and improve yourself with them.
Well, I hope that I could help somehow.
In relation to your last question, I have never experienced to cook to a husband of mine, even why I never had one and I am a heterossexual man. Ha, ha, ha!
I wish good luck to you!
