There are a few things to understand about strength (or really any training).
1. You should only be training as much as you can recover. This depends on the length and intensity of the training bout. For example, @ 25 yrs old I could hit legs and upper body 2x a week, albeit the second training session was much less intense than the first session. At 37 I can still do it 2x a week, but I really need to be mindful of what is in the 2nd session. Most times I forgo the 2nd session and hit cardio more. Remember, the timing and number of workouts is about PROGRESS. If you are not recovering, dial back on something, either intensity, frequency, duration etc.
2. Cardio will affect your ability to strength train, even as low as Zone 2. Walking or other low level recovery stuff is great tho.
3. It is better to slightly undertrain than it is to slightly overtrain. You need a "standard" for weight training where if you are not hitting it you have a built in deload.
4. Fuel yourself. @Larry Bartlett and @V2Pnutrition give good info above.
5. Know the difference between "training" and just daily activity. At your age you need to be more active, but training is different. Training is purposeful, daily activity should be a default.
