Good but cost-effective impact driver.
Discussion
Not sure that’s exactly what you need, but I just purchased a Parkside (Lidl) one to swap wheels. They’ll only do about a fourth of their rated torque (maybe that’s true of other brands?), but they’re well made and cheap. Paid 90€ for the biggest one with a battery and charger. That’ll handle lug nuts easily.
I am making a price / quality judgement on this one. But this is the sort of thing I have in mind.

You will be lucky if the battery lasts 6 months.https://www.amazon.co.uk/Cordless-Battery-6000mAh-...
Buy one of these it has JIS bits and the battery never goes flat.

The bits will be rubbish and I highly doubt it delivers its claimed torque. Even if it does I doubt it will offer you enough control for the type of usage you're suggesting. https://www.amazon.co.uk/Cordless-Battery-6000mAh-...
I wouldn't expect much from the bits that come with any impact driver, and in any case they are consumables. Buy a box of decent quality bits for the type of fastener you will be undoing most frequently - I have some boxes of DeWalt and Makita bits which seem to do OK, don't know if others are better.
As has already said you don't need, or should use, an impact driver on some screws on a motorbike. You don't say what screws these are (more than likely to be JIS if it is a Japanese bike) but why would they need a torque that only an impact driver could achieve (impact drivers are exactly precise at doing this though). Use 420Nm on a screw and you'll mash it up nice and quickly.
You need to know what the screws are and what torque they need to be (if anything specific). Then buy a suitable torque wrench from Amazon and a set of correct bits for the screw head type.

A range of screws. But immediately I am thinking about bar end weights. On the bike that arrives tomorrow they are notoriously “sticky” and if they won’t give readily I want something that will “press and turn” simultaneously, like my old manualYou need to know what the screws are and what torque they need to be (if anything specific).

I suppose loosening can work with an impact driver but you'll fImpact driver used to.
k the screw heads up 99% of the time, and screws really aren't things designed to really be tightened by an impact driver.For that specific use, loosening the cross-head machine screws on Jap 'bikes, you really need no more than the good ol' fashioned clout-type impact driver, and yes, use with good quality bits. You normally only need one sharp tap to get them moving.
The drivers are as cheap as chips (like most things, cheaper on Ebay than Scamazon
) and I would suggest that you buy the (branded) bits separately. Remember that those Jap cross-heads are invariably 'Phillips', not 'Pozidrive'; it's really important that you check they are a snug fit on the bit before applying any force.
I take it that you know how to use a manual impact driver correctly?... loading it up in the direction of desired travel?...
I've always replaced those Jap screws with socket head screws ('allen bolts') on every bike I've owned, makes it easier next time.
Good luck.

Not actually true though is it?They are frequently JIS which is not Philips & also not Posidrive.
Use the correct bits or you will absolutely increase the chance of rounding off the slots.

It is pretty impossible for us to know without seeing the screw heads.
Is the bike Japanese, are the screws original to the bike? If yes and yes I would say there is a good chance that they are JIS. If they are aftermarket addons it is likely that whoever added them used JIS screws. Replacing with inner hex headed screws (as already suggested) is probably a good idea.
