This, and also working part time would become a lot more feasible. I would imagine there would be quite a bit of pressure to improve working conditions as well, which wouldn't exactly be a bad thing. A lot more hours would be spent on things people consider meaningful, and bullshit jobs would have to be compensated appropriately, which to me feels like a win for society collectively.

One caveat though is that for abolishing minimum wages to be safe the UBI has to be high enough to be actually livable, and would likely be a target of constant politicking. A model I've been thinking about would be to set the level of UBI as a percentage of GDP, distributed evenly across the population, which to me would feel fair but may have practical issues I don't see. It would create a sense of everyone benefiting from collective success, which appeals to me.
