I think these Betashares ETFs are strong buys this month

Exchange-traded funds (ETFs) can be a great way to invest for the long term without having to pick individual shares.

And with November underway, there are three Betashares ETFs I think are worth considering.

Each offers exposure to a different investment opportunity, and I believe all three could reward patient investors over the coming years.

Betashares Australian Quality ETF (ASX: AQLT)

The first Betashares ETF I'd buy this month is the AQLT ETF, which takes a selective approach to investing in Australian shares.

Rather than simply owning the largest companies on the ASX, it focuses on businesses with strong financial characteristics.

Its index selects 40 Australian companies based on profitability, financial strength, and earnings stability.

I like this approach because businesses that consistently generate strong returns and maintain healthy balance sheets are often better positioned to navigate difficult economic conditions. And they can have more flexibility to reinvest in growth when opportunities arise.

The ETF provides exposure to established businesses such as CSL Ltd (ASX: CSL), Wesfarmers Ltd (ASX: WES), and Commonwealth Bank of Australia (ASX: CBA).

I think this demonstrates the financial qualities the fund is looking for.

Of course, focusing on quality doesn't guarantee outperformance, and the ETF's relatively concentrated portfolio means individual holdings can influence returns.

Nevertheless, I like its disciplined approach to selecting Australian shares and would be happy to buy it for the long term.

Betashares Global Defence ETF (ASX: ARMR)

Another Betashares ETF I rate highly is the ARMR ETF, which provides exposure to leading global defence companies.

I believe the defence industry could experience substantial growth over the next decade as governments increase military spending and modernise their equipment.

For example, last year NATO announced that its members have committed to lifting defence and security-related investment to 5% of GDP by 2035, including at least 3.5% for core defence requirements.

That's a significant commitment that could translate into years of demand for military equipment, advanced technology, and defence systems.

And the ARMR ETF offers investors exposure to companies positioned to benefit. Its holdings include businesses involved in aircraft, missiles, military technology, and other defence equipment.

I like that many of these companies have established relationships with governments and opportunities to secure long-term contracts.

However, defence shares can be volatile, especially when expectations for government spending are already high. And with the fund focused on a single industry, I would view it as a higher-risk investment.

Still, I believe the long-term outlook for defence spending makes this ETF worth considering.

Betashares Global Shares ETF (ASX: BGBL)

My final pick is the BGBL ETF, which I think is an excellent option for gaining exposure to the world's leading companies.

It tracks an index of approximately 1,300 shares across more than 20 developed markets, excluding Australia.

That includes major companies operating across technology, healthcare, financial services, consumer products, and industrials.

I like this diversification because it gives investors exposure to businesses and industries that are less represented on the ASX.

The ETF also provides opportunities to benefit from global trends such as artificial intelligence (AI), digitalisation, and healthcare innovation.

And there's another reason I rate this Betashares ETF highly. Its management fee is just 0.08% per annum, making it an inexpensive way to access international shares.

Of course, the fund has substantial exposure to the United States, while currency movements can also affect returns. However, I think its combination of broad international exposure and low fees makes it a strong long-term investment.

Foolish takeaway

I think all three Betashares ETFs deserve consideration this November.

For investors who want to build wealth over many years, I believe having exposure to strong businesses and industries with attractive growth opportunities is a sensible approach.

And while market conditions will inevitably change, I'd be comfortable buying these funds with a long-term view.
