Best of luck, Tom! You'll find a rich resource of experience here on the Forum, and a well-informed and friendly group who will be more thank happy to offer suggestions based on real-world, personal experience.
It surely *can* be confusing to choose the "right" light for your needs, but there's good news: There are more good lights available now than in the past, and it is harder and harder to go truly wrong.
New and improved products are being introduced and existing designs refined every six months to annually, so the perfect solution is likely either available or right around the corner.
One thing to consider a (head) light that incorporates gadget-charging capability -- or not. I made the choice to keep my lighting separate from my charging options so I could upgrade either element, but there's a good argument to go with all-in-one solutions as well (and a light with charging capability can be less expensive overall than separate solutions).
Happy New Year, happy cycling, happy buying!
Dan.
