There are loads of houseplants on the market so you really need to think about things like budget, aspect (light levels and direct sun or not), ambient temperatures, hummidity (som edo best in bathrooms and some in dry air), how much care and attention they need (are you there all the time or occasionally absent for a week or two or more?) etc.
The RHS has this initial advice and then you can search its site for more specific info - https://www.rhs.org.uk/advice/profile?PID=947
As for herbs, it depends on what you like to cook and again on how well you can care for them. eg Plants like mint and basil need more moisture and less direct sun than thymes. but none is worth growing if you won't use it. Then there's parsley, coriander, rosemary, bay, French tarragon, which are all essential plants for my kitchen but maybe not yours.
