How does Ultra-Wideband (UWB) compare to NFC?

UWB is very distinct technology than NFC, here is how:

UWB operates over a wide frequency spectrum (e.g. 3.1 GHz to 10.6 GHz) and can deliver very high data rates, much higher than NFC.
NFC operates at a fixed frequency (13.56 MHz), at low data rates.
UWB supports accurate ranging and positioning capabilities (centimeter-level accuracy), which NFC cannot; NFC is mainly for simple short-range communication.

What is the difference between Bluetooth and NFC?

The difference between BLE and NFC is as follows:

Bluetooth (or Bluetooth Low Energy, BLE) works over a relatively longer range (tens to hundreds of meters) and supports higher data transfer rates.
NFC operates only over very short distances (a few centimetres); ideal for very close-range data exchange or tap-to-connect scenarios.
NFC setup is simpler, often requires little or no pairing, and consumes very low power, making it suitable for quick, low-data tasks (e.g. payments, access control).

What frequency-based classifications exist for RFID tags and how do they affect read range?

RFID tags are classified by frequency as well:

Low Frequency (LF): around 125 kHz; generally short read range (few centimeters), often used in access tags, identification cards.
High Frequency (HF): around 13.56 MHz (same as many NFC-type tags); read range up to ~1 meter; used for access control, event cards, ID cards.
Ultra-High Frequency (UHF): 860–960 MHz (ISM band globally); passive UHF tags offer read range ~15 m, active UHF tags up to ~100 m

What kinds of RFID readers are available and How should one choose a specific type?

RFID readers are available as handheld readers, fixed readers, USB readers, or integrated readers (with built-in antenna). Depending on your use-case, for example, mobile asset auditing, fixed gatewise scanning, or desktop-based reading; you should choose a reader type whose frequency matches your tags.
