...at least not right away.

I often "roll-my-own" in that I solder an 0805-packaged 1K0 resistor between pins 23 and 12 and one between pins 11 and 10, and 150 pF 0805=packaged cap between pins 12 and 11, all on a DIL-packaged 74xx04. I then solder the crystal pins between pins 13 and 10. This oscillator is then buffered by connecting pin 9 to pin 10, which puts the output on pin 8, which is exactly where it is found on a crystal oscillator in the DIP-14. With frequencies below 8 MHz and above 15 MHz, I've had to change the cap value on occasion, but I find this works pretty well regardless of the component technology, with the exception of 70C04 (CD40106).

If concerned about excessive noise, I'd connect pins 1, 3,and 5 to Vcc.

There is a wide range of things that can be done if you use an external crystal oscillator, that cannot be accomplished with the built-in oscillator. One issue is the startup time if you cycle power to the MCU.
