As someone who just spent the last 4 years in Cleveland (for school), I want to comment on professional environment of the city for those interested in tech careers. The number of companies is pretty low, and the professional environment is far more conservative/traditional than what you'd see in the big tech hubs. Also if you look at BLS data, there is a below average number of tech jobs when compared to other economic regions.
The kinds of industries that dominate in NE Ohio are either advanced chemical manufacturing and medicine through the Cleveland Clinic.
Other comments both positive and negative:
The RTA is pretty bad, but it isn't bad at all by American public transportation standards.
The city has amazing opportunities within the arts for a city of it's size, the museums are really great and free. Additionally, the Cleveland orchestra is relatively cheap to attend and they are one of the best orchestras in the world. Lastly, big acts and shows do come to playhouse square.
Cleveland has some really great public events, Bright Winter and Ingenuity Fest are absolutely amazing. It has an amazing food scene that is constantly expanding, where waiters at top restaurants can also afford a home in the city.
Lastly, for a city that is constantly ranked as one of most out of shape cities in the country, people are so incredibly passionate about this place. In bigger, more global cities, there is less of a desire among the general population to improve the community at large. In Cleveland, everyone is on the same team.
Overall, if you are a person who likes small cities (I personally am not), Cleveland is a pretty great choice overall, especially if cost of homeownership is an important factor in the city you choose to live in.
