Shared e-bike/e-scooter are the most convenient solution to the last mile (there's very little alternative, actually).
The last mile problem is very concrete, especially if it's a routine two-way trip; without e-transport, it's 30/40 minutes total for each trip (on foot or bus, the latter also being nondeterministic), versus 10 minutes of ebike/escooter (quite deterministic). It's a lot of time saved.
Time-wise, Uber sits midway between bus and e-transport (there's waiting time, depending on the location), but it's considerably more expensive - in my city, e-transport costs around 0.25$ per minute, which is convenient.
Having said that, I do support either very strict regulation or straigh-out ban of e-scooters. It seems to be a teenage thing (adults hardly use them), and it's typically used very recklessly. Additionally, I prefer shared e-bikes anyway, because they're faster and more comfortable on poorly paved roads.
Without any form of e-transport, the only alternative is to bring one's own bike/e-scooter on public transport, which is possible in some cities (where the metro is large and not busy), but not so practical and limited to metro and tram.
