Is the SE 3 worth it over the SE 2?

Yes if you want the Always-On display, the S10 chip and fast charging. The SE 2 still covers basic tracking for less.

Does the Apple Watch SE 3 have an ECG or blood oxygen sensor?

No. It has heart rate, irregular rhythm and sleep apnea notifications, but no ECG app and no blood oxygen measurement.

How long does the battery last?

Apple rates it at up to 18 hours of normal use and up to 32 hours in Low Power Mode. Expect to charge it most nights.

Do I need the cellular model?

Only if you want calls, messages and music without your iPhone nearby. The GPS model is cheaper and covers most workouts.

What wrist sizes does it fit?

The 44mm case fits wrists from 140 to 245mm with the right band.
