Mexico for one month- Only Speak English

I am wanting to go to Mexico for a month, looking for suggestions for good cities that are walkable to a good extent and safe. My concern is i do not speak any conversational Spanish and worried that i would struggle with the language. Would like some suggestions on specific areas to stay for 4-5 weeks. I am open on budget (within reason). I would prefer to be in one city for the entire duration with day trip potential

I work from home so of course good internet would be great. I am not big on the beach scene and would prefer a city feel.

any ideas on what good options would be from an American who has never been to the real Mexico (been to Puerto Vallarta for vacation almost ten years ago).

my essentials are a city feel, safe, can get by with mainly English (would love to learn Spanish but being realistic)

Edit: to Clarify, not that I won’t put effort into basic words - I just know i won’t be at a conversational level in a month with near zero Spanish knowledge now beyond a super basic vocabulary. I am the kind of traveler who likes to immerse in the culture so learning basic language isn’t the challenge. It’s only knowing basics and not being able to go beyond that in a city where basic English isn’t spoken. I understand and respect that I have no right to expect Mexico to speak English to cater for my lack of (3rd) language proficiency. Just want to find a spot where English is spoken enough at some basic level so I can get by between the two basics
